Demand Letter for Child Support in the Philippines

I. Introduction

A demand letter for child support is one of the most common first steps taken by a parent, guardian, or custodian when the other parent refuses, neglects, delays, or gives insufficient financial support for a child.

In the Philippines, the obligation to support a child is not optional. It is imposed by law, arises from family relationship, and exists regardless of whether the parents are married, separated, annulled, estranged, or never married at all. A child has the right to receive support from both parents, and a parent cannot avoid that duty simply by refusing communication, starting a new family, becoming unemployed by choice, or denying responsibility without legal basis.

A demand letter is not always required before filing a case, but it is often useful. It formally states the child’s need for support, identifies the legal basis of the claim, demands payment, proposes an amount or arrangement, and creates a written record that the supporting parent was asked to comply before legal remedies were pursued.

This article discusses the nature, purpose, contents, legal basis, practical use, and possible consequences of a demand letter for child support in the Philippine context.

II. What Is Child Support?

Child support is the legal obligation to provide for the needs of a child. Under Philippine law, support includes more than food or allowance.

Support generally includes everything indispensable for:

  1. sustenance;
  2. dwelling;
  3. clothing;
  4. medical attendance;
  5. education;
  6. transportation;
  7. personal care;
  8. other needs consistent with the family’s financial capacity and social circumstances.

Education includes schooling or training for some profession, trade, or vocation, even beyond the age of majority, if the child’s circumstances reasonably require it.

Child support is based on the child’s needs and the parent’s financial capacity. It is not meant to punish the parent. It is meant to protect the child.

III. Who Has the Right to Receive Child Support?

A child has the right to receive support from his or her parents.

This includes:

  1. legitimate children;
  2. illegitimate children;
  3. legitimated children;
  4. legally adopted children;
  5. children whose parents are married;
  6. children whose parents were never married;
  7. children of separated parents;
  8. children of annulled or void marriages, subject to applicable rules;
  9. minor children;
  10. children of legal age who still need education or are incapable of self-support under proper circumstances.

The child’s right to support exists because of filiation, not because of the status of the parents’ relationship.

IV. Who May Send a Demand Letter for Child Support?

A demand letter may be sent by:

  1. the mother;
  2. the father;
  3. the child’s legal guardian;
  4. a person exercising substitute parental authority;
  5. the child, if already of legal age and claiming support for education or necessary needs;
  6. a lawyer representing the child or custodial parent;
  7. a social worker or authorized representative in certain cases;
  8. a government agency or women and children protection office, depending on the circumstances.

In practice, the custodial parent usually sends the letter because that parent directly shoulders the child’s daily expenses.

V. Against Whom Is the Demand Letter Sent?

The demand letter is usually addressed to the parent who is not providing adequate support.

It may be sent to:

  1. the biological father;
  2. the biological mother;
  3. an adoptive parent;
  4. a parent living separately from the child;
  5. a parent working abroad;
  6. a parent who has a new family;
  7. a parent who has stopped giving allowance;
  8. a parent who gives irregular or insufficient support;
  9. a parent denying responsibility despite prior acknowledgment;
  10. a parent who agreed to support but failed to comply.

A demand letter should be addressed to the proper person and should state the basis of the claim clearly.

VI. Legal Basis of Child Support

The principal legal basis for child support in the Philippines is the Family Code.

The Family Code imposes support obligations among certain relatives, including parents and their legitimate and illegitimate children.

The duty of parents to support their children is also connected with:

  1. parental authority;
  2. the best interest of the child;
  3. the child’s right to survival and development;
  4. the State’s policy to protect children and the family;
  5. civil liability arising from family relations;
  6. criminal and protective laws in cases of abandonment, abuse, or economic abuse.

Other relevant legal frameworks may include:

  1. the Civil Code;
  2. the Rules of Court;
  3. laws protecting women and children;
  4. laws against violence against women and their children;
  5. laws on solo parents;
  6. adoption laws;
  7. social welfare and child protection rules;
  8. overseas employment and migrant worker procedures, where relevant.

VII. Is a Demand Letter Required Before Filing a Case?

A demand letter is not always an absolute legal requirement before every possible child support action. A parent or child may file a proper case when the right to support exists and the other parent refuses or fails to provide.

However, a demand letter is often advisable because it:

  1. gives the other parent a chance to comply voluntarily;
  2. documents refusal or neglect;
  3. establishes the date of demand;
  4. supports a later claim for arrears;
  5. shows good faith;
  6. clarifies the amount requested;
  7. helps avoid litigation if the other parent cooperates;
  8. creates evidence for barangay, prosecutor, court, or protection order proceedings;
  9. may support a claim under laws involving economic abuse;
  10. may be used in settlement discussions.

In many practical situations, the demand letter becomes the first documentary proof that the custodial parent made a clear, formal request for support.

VIII. Purpose of a Demand Letter for Child Support

A demand letter serves several purposes.

A. To Assert the Child’s Right

The letter states that the child is legally entitled to support and that the recipient has a duty to provide it.

B. To Request a Specific Amount

A demand letter should ideally state a specific monthly amount or at least a proposed contribution based on actual expenses.

C. To Demand Payment of Arrears

If the parent has failed to support the child for months or years, the letter may demand payment of past unpaid support.

D. To Request Reimbursement

The custodial parent may request reimbursement for expenses already advanced, such as tuition, hospital bills, medicine, rent, food, or school supplies.

E. To Set a Deadline

The letter usually gives a reasonable period to comply, such as five, seven, ten, or fifteen days from receipt.

F. To Warn of Legal Action

The letter may state that failure to comply may result in legal action, including civil, criminal, or protective remedies where applicable.

G. To Encourage Settlement

A well-written demand letter may open the door to negotiation, mediation, or a written support agreement.

IX. What Should Be Included in the Demand Letter?

A good demand letter for child support should be clear, factual, respectful, and complete.

It should usually contain:

  1. date of the letter;
  2. name and address of the recipient;
  3. name of the child;
  4. date of birth of the child;
  5. relationship of the recipient to the child;
  6. facts showing filiation or acknowledgment;
  7. statement that the child is in need of support;
  8. summary of monthly expenses;
  9. amount demanded;
  10. payment method requested;
  11. request for regular monthly support;
  12. demand for unpaid support or reimbursement, if any;
  13. deadline to comply;
  14. warning that legal remedies may be pursued;
  15. contact details of sender or counsel;
  16. attachments, if appropriate.

The letter should not contain unnecessary insults, threats, defamatory accusations, or emotional attacks. Its purpose is to create a strong legal record, not to escalate personal conflict.

X. Proof of Filiation

Before demanding child support, the claimant must be prepared to prove that the child is legally related to the parent from whom support is demanded.

For the mother, maternity is usually shown by the child’s birth certificate.

For the father, proof of paternity may include:

  1. the child’s birth certificate signed by the father;
  2. acknowledgment in a public document;
  3. admission in a private handwritten instrument signed by the father;
  4. use of the father’s surname with proper acknowledgment;
  5. written communications admitting paternity;
  6. support previously given by the father;
  7. school records naming him as father;
  8. medical records;
  9. DNA evidence, where necessary;
  10. court judgment establishing filiation.

For illegitimate children, proof of filiation is especially important. A demand letter may attach a copy of the child’s birth certificate or mention that documents proving filiation are available.

XI. Demand Letter for a Legitimate Child

For a legitimate child, the demand letter usually relies on:

  1. the marriage of the parents;
  2. the child’s birth during the marriage;
  3. the child’s birth certificate;
  4. the parent’s legal obligation under the Family Code;
  5. the child’s actual needs.

The letter may be sent after separation, abandonment, failure to provide, or refusal to contribute to household and educational expenses.

Even if the parents are legally married and not annulled, one parent may demand support from the other if the latter is not contributing to the child’s needs.

XII. Demand Letter for an Illegitimate Child

An illegitimate child is also entitled to support from the biological parent, but filiation must be established.

The demand letter should be more careful in stating:

  1. the child’s full name;
  2. the child’s date of birth;
  3. the facts of paternity or maternity;
  4. any acknowledgment made by the parent;
  5. prior support, if any;
  6. documents proving filiation;
  7. the child’s present needs;
  8. the amount demanded.

If paternity is disputed, the demand letter may request voluntary acknowledgment, support, and cooperation in DNA testing or mediation.

A father cannot defeat the claim merely by saying that the child is illegitimate. Illegitimate children are still entitled to support, although evidentiary issues may arise.

XIII. How Much Child Support May Be Demanded?

Philippine law does not impose a fixed universal percentage, such as 10%, 20%, or 30% of income, for all child support cases.

The amount depends on two main factors:

  1. the needs of the child; and
  2. the resources or means of the parent obliged to give support.

This means child support is proportional. A wealthy parent may be required to give more than a minimum-wage earner. But even a parent with modest income may still be required to contribute according to ability.

A demand letter should ideally include a realistic computation of the child’s monthly needs.

XIV. Common Expenses Included in Child Support

The demand may include the child’s share of:

  1. food and groceries;
  2. milk, vitamins, and supplements;
  3. clothing;
  4. rent or housing;
  5. electricity and water;
  6. school tuition;
  7. school supplies;
  8. books and uniforms;
  9. transportation;
  10. internet for schooling;
  11. medical checkups;
  12. medicines;
  13. hospital bills;
  14. dental care;
  15. therapy or special needs support;
  16. caregiver or yaya expenses;
  17. extracurricular activities, if reasonable;
  18. insurance or health coverage;
  19. emergency expenses;
  20. other necessary living expenses.

The demand should distinguish between ordinary monthly support and special or extraordinary expenses.

XV. Sample Monthly Expense Breakdown

A demand letter is stronger when it contains a breakdown.

Example:

Expense Monthly Amount
Food and groceries ₱8,000
School expenses ₱6,000
Transportation ₱3,000
Clothing and personal needs ₱2,000
Medical and vitamins ₱2,500
Housing and utilities share ₱5,000
Miscellaneous child-related expenses ₱1,500
Total ₱28,000

The demand may then request that the other parent contribute a specific share, such as ₱14,000 monthly, or a higher or lower amount depending on the parent’s income and prior arrangements.

XVI. Can the Demand Include Past Unpaid Support?

Yes. The letter may demand arrears or reimbursement if the other parent failed to support the child.

For example, if the parent failed to give support for six months and the demanded amount is ₱15,000 per month, the letter may demand:

₱15,000 × 6 months = ₱90,000 in unpaid support

However, the claimant should support the demand with receipts, records, prior messages, or proof that the expenses were actually incurred.

The letter may demand both:

  1. payment of arrears; and
  2. regular monthly support going forward.

XVII. Can Support Be Increased or Decreased?

Yes. Child support is not permanently fixed. It may be adjusted depending on changes in:

  1. the child’s needs;
  2. the child’s age;
  3. schooling level;
  4. medical condition;
  5. inflation and cost of living;
  6. the parent’s income;
  7. the parent’s employment;
  8. the parent’s other legal obligations;
  9. special needs or emergencies.

A demand letter may request an increase if the current support is no longer enough.

Likewise, the supporting parent may ask for adjustment if there is a genuine change in financial capacity. But the parent should not simply stop paying without agreement or court approval.

XVIII. Can the Parent Give In-Kind Support Instead of Money?

Support may sometimes be given in kind, such as directly paying tuition, rent, groceries, medicine, or health insurance.

However, in-kind support should be clear, documented, and actually beneficial to the child.

Problems arise when a parent claims to have given support but provides only occasional gifts, toys, snacks, or discretionary items. Gifts are not always the same as support.

A demand letter may specify whether support should be paid:

  1. in cash;
  2. by bank transfer;
  3. by e-wallet;
  4. by direct tuition payment;
  5. by direct medical payment;
  6. partly in cash and partly direct payment.

The safest arrangement is documented and traceable.

XIX. Child Support and Visitation

A parent cannot generally refuse child support because he or she is not allowed to visit the child. Support and visitation are separate issues.

Likewise, a custodial parent should not use the child as leverage by denying reasonable visitation solely because support is unpaid, unless safety or legal concerns exist.

The child’s right to support belongs to the child. It is not payment for visitation rights.

If visitation, custody, or parental authority is disputed, those issues should be addressed separately through agreement, barangay proceedings, social welfare intervention, or court action.

XX. Common Defenses Raised by the Parent Asked to Pay

A recipient of a demand letter may respond with defenses such as:

  1. denial of paternity;
  2. lack of proof of filiation;
  3. unemployment;
  4. low income;
  5. already supporting another family;
  6. excessive amount demanded;
  7. lack of receipts;
  8. the custodial parent allegedly misuses the money;
  9. the child is already of legal age;
  10. the child is not studying;
  11. prior informal support was already given;
  12. the custodial parent refuses visitation;
  13. the demand is unreasonable.

Some defenses may reduce or clarify the amount, but they do not automatically erase the duty to support if filiation and need are established.

XXI. Unemployment or Lack of Income

A parent cannot automatically avoid support by claiming unemployment.

The court or agency may look at:

  1. actual earning capacity;
  2. employability;
  3. education and skills;
  4. lifestyle;
  5. assets;
  6. business interests;
  7. remittances;
  8. bank records;
  9. voluntary unemployment;
  10. concealment of income.

A parent who intentionally avoids work to escape support may still be held responsible according to earning capacity and circumstances.

However, genuine inability to pay may affect the amount and schedule of support.

XXII. Parent Working Abroad

Many child support disputes involve a parent working abroad.

A demand letter may be sent through:

  1. email;
  2. courier;
  3. registered mail;
  4. messaging application, with proof of receipt;
  5. the parent’s Philippine address;
  6. the parent’s overseas address;
  7. counsel or authorized representative;
  8. employer channels, in proper cases.

If the parent is an overseas Filipino worker, additional remedies may involve overseas employment records, consular assistance, or legal proceedings in the Philippines.

The demand letter should still state the amount, child’s needs, payment channels, and deadline.

XXIII. Demand Letter and Violence Against Women and Children

Failure to provide financial support may, in certain circumstances, be treated as economic abuse under laws protecting women and children.

Economic abuse may include acts that make or attempt to make a woman or child financially dependent, including withdrawal of financial support, deprivation of financial resources, or preventing employment or livelihood.

A demand letter may be relevant evidence if a case for protection order or criminal complaint is later pursued.

However, not every unpaid support dispute automatically becomes a criminal case. The facts matter, including relationship, child involved, intent, pattern of abuse, capacity to provide, and refusal or deprivation.

XXIV. Barangay Conciliation

Some disputes may pass through barangay conciliation if the parties are covered by the Katarungang Pambarangay system.

However, family, child support, violence, protection order, and urgent child welfare issues may require special handling. Certain cases may be exempt or may proceed directly to court or proper agencies depending on the nature of the relief sought.

A demand letter can be useful before barangay proceedings because it defines the issue and amount requested.

If a settlement is reached at the barangay level, it should be put in writing and should clearly state:

  1. amount of monthly support;
  2. due date;
  3. payment method;
  4. arrears, if any;
  5. school and medical expenses;
  6. visitation arrangements, if included;
  7. consequences of default.

XXV. Court Action for Support

If the demand letter is ignored, the child or custodial parent may consider filing an action for support.

A court may order:

  1. monthly support;
  2. provisional support while the case is pending;
  3. payment of arrears;
  4. direct payment of school or medical expenses;
  5. support pendente lite;
  6. other appropriate relief.

The court considers the child’s needs and the parent’s resources.

A demand letter may be attached as evidence showing prior demand and refusal.

XXVI. Support Pendente Lite

Support pendente lite means support while the case is pending.

Because court cases can take time, a claimant may ask the court for temporary support during the litigation. This is important because children need food, schooling, and medical care immediately, not only after final judgment.

Documents supporting the request may include:

  1. birth certificate;
  2. proof of filiation;
  3. expense breakdown;
  4. receipts;
  5. school assessment;
  6. medical records;
  7. proof of the other parent’s income;
  8. prior messages or admissions;
  9. demand letter and proof of receipt.

XXVII. Criminal Complaint for Abandonment or Economic Abuse

Depending on the facts, failure to support may lead to criminal or protective remedies.

Possible legal bases may involve:

  1. economic abuse under laws protecting women and children;
  2. abandonment or neglect under penal or child protection laws;
  3. violation of court orders;
  4. contempt of court;
  5. other child welfare offenses.

The demand letter can help show that the parent knew of the obligation and refused or failed to comply.

However, criminal cases require proof of the elements of the offense. A simple inability to pay due to genuine poverty may be treated differently from deliberate refusal despite capacity.

XXVIII. Demand Letter From a Lawyer

A lawyer’s demand letter may carry more legal weight because it signals readiness to proceed with formal remedies.

A lawyer can:

  1. identify the legal basis;
  2. compute support and arrears;
  3. organize evidence;
  4. avoid defamatory or harmful language;
  5. demand compliance within a clear period;
  6. propose settlement;
  7. warn of civil and criminal remedies;
  8. prepare the next legal step if ignored.

However, a demand letter does not need to come from a lawyer to be valid. A parent or guardian may send one directly.

XXIX. Tone of the Demand Letter

The tone should be firm but professional.

Avoid statements such as:

  1. insults;
  2. threats of public humiliation;
  3. threats to contact the employer without legal basis;
  4. threats to post on social media;
  5. exaggerated accusations;
  6. profanity;
  7. emotional attacks;
  8. statements that may be considered extortion or harassment.

A demand letter should focus on the child’s needs and the parent’s legal duty.

A calm and well-documented letter is more useful in court than an angry message.

XXX. Attachments to the Demand Letter

Useful attachments may include:

  1. child’s birth certificate;
  2. acknowledgment document;
  3. school assessment or tuition statement;
  4. receipts for tuition and school supplies;
  5. medical bills;
  6. pharmacy receipts;
  7. rent or utility bills showing child’s household expenses;
  8. summary of monthly expenses;
  9. proof of prior support agreement;
  10. screenshots of admissions or promises to support;
  11. proof of unpaid amounts;
  12. bank details for payment.

Do not attach sensitive documents unnecessarily if privacy or safety is a concern. Copies should be clear and relevant.

XXXI. Proof of Service or Receipt

A demand letter is more useful if the sender can prove that the other parent received it.

Methods include:

  1. personal delivery with signed receiving copy;
  2. registered mail;
  3. courier with delivery confirmation;
  4. email with acknowledgment;
  5. messaging application showing delivery and read receipts;
  6. delivery through counsel;
  7. notarized affidavit of service, where appropriate.

A copy of the letter should be kept along with proof of receipt.

If the other parent refuses to receive the letter, the sender should document the refusal.

XXXII. Should the Demand Letter Be Notarized?

A demand letter does not generally need to be notarized to be effective.

However, notarization may be useful if the sender wants to strengthen the evidentiary value of the document, especially regarding the date, identity of the signatory, and seriousness of the demand.

If the letter includes sworn statements, it may be prepared as an affidavit or verified demand. But an ordinary signed letter with proof of delivery is often enough for practical purposes.

XXXIII. Can a Demand Be Sent by Text, Email, or Chat?

Yes, a demand may be communicated electronically. Messages through email, SMS, Viber, Messenger, WhatsApp, or other platforms may serve as evidence that support was demanded.

However, for a more formal record, a written demand letter is preferable.

A good practice is to send the signed demand letter by email or courier, then send a message informing the parent that a formal demand has been sent.

Electronic messages should be preserved through screenshots, exports, and backups.

XXXIV. Demand Letter Versus Support Agreement

A demand letter is a request or assertion of a claim. A support agreement is a mutual arrangement.

A support agreement may be reached after the demand letter and should include:

  1. amount of monthly support;
  2. date of payment;
  3. bank or e-wallet details;
  4. sharing of tuition;
  5. sharing of medical expenses;
  6. treatment of arrears;
  7. annual increase or adjustment;
  8. proof of payment;
  9. consequences of default;
  10. visitation or custody provisions, if appropriate;
  11. signatures of parties;
  12. notarization, if desired.

A notarized support agreement may be useful evidence, but court approval may still be necessary in certain disputes or when enforcement is needed.

XXXV. Can Parents Waive Child Support?

Parents cannot validly waive the child’s right to support in a way that prejudices the child.

A custodial parent cannot permanently bargain away the child’s legal right to support simply for personal convenience or settlement. The right belongs to the child.

A parent may agree on a practical arrangement, but the child’s needs remain the controlling consideration.

If the agreed support becomes insufficient, an increase may be demanded.

XXXVI. Child Support and Custody Agreements

Demand letters sometimes include custody and visitation issues. This is possible, but the support demand should remain clear.

A parent should avoid making support conditional on custody concessions.

For example, the supporting parent should not say, “I will only support if I get the child every weekend,” and the custodial parent should not say, “You cannot see the child unless you pay first,” unless there are safety or court-order concerns.

Support is for the child. Custody and visitation are governed by the child’s best interest.

XXXVII. Support for a Child of Legal Age

A child who has reached eighteen may still be entitled to support in appropriate circumstances, especially for education or training for a profession, trade, or vocation.

For example, a college student may still demand support from a parent if still dependent and pursuing reasonable education.

The demand letter should explain:

  1. the child’s age;
  2. school enrollment;
  3. course or training;
  4. expenses;
  5. continued dependency;
  6. parent’s capacity to contribute.

However, an adult child who is already self-supporting may have a weaker claim.

XXXVIII. Child With Special Needs

For a child with disability, chronic illness, developmental delay, or special needs, support may include additional expenses such as:

  1. therapy;
  2. special education;
  3. medical consultations;
  4. assistive devices;
  5. medication;
  6. caregiver costs;
  7. special transportation;
  8. nutrition;
  9. rehabilitation;
  10. long-term care.

The demand letter should attach medical certificates, therapy assessments, prescriptions, and cost estimates where available.

XXXIX. Child Support During Pregnancy

A pregnant woman may demand support related to pregnancy and childbirth from the father of the unborn child, depending on circumstances and proof.

Expenses may include:

  1. prenatal checkups;
  2. vitamins and medicines;
  3. laboratory tests;
  4. ultrasound;
  5. hospital expenses;
  6. delivery costs;
  7. newborn needs.

After birth, the child’s support claim becomes clearer through the birth certificate and proof of filiation.

If paternity is disputed, DNA testing may become relevant after birth.

XL. Child Support and DNA Testing

When paternity is denied, DNA testing may be requested.

A demand letter may state that the father is requested to provide support and, if he disputes paternity, to cooperate in lawful DNA testing.

However, DNA testing typically requires consent or court involvement. A person cannot simply force another person to submit to testing without proper legal basis.

Refusal to undergo DNA testing may be considered in legal proceedings depending on the circumstances.

XLI. Demand Letter When Paternity Is Denied

If the father denies paternity, the demand letter should avoid overstatement and focus on known facts and evidence.

It may state:

  1. the history of the relationship;
  2. the date of birth of the child;
  3. acknowledgment made by the father, if any;
  4. prior support given;
  5. documents showing paternity;
  6. willingness to submit to lawful DNA testing;
  7. demand for support pending resolution, if appropriate;
  8. warning that legal remedies may be pursued.

If paternity is seriously disputed, filing a court action may be necessary.

XLII. Demand Letter When the Parent Has a New Family

A parent’s new family does not erase the obligation to support an existing child.

However, the parent’s total financial obligations may be considered in determining the amount.

A demand letter may respectfully state that the child’s right to support continues regardless of the parent’s new relationship, marriage, or additional children.

The law requires proportionality, not abandonment of one child in favor of another.

XLIII. Demand Letter When the Parent Is Married to Someone Else

A child born outside marriage may still demand support from the biological parent if filiation is proven.

However, disputes may arise because of the parent’s existing legal family. The letter should be carefully written to avoid unnecessary scandal, defamation, or harassment.

It should focus on:

  1. the child’s identity;
  2. proof of filiation;
  3. the child’s needs;
  4. the parent’s duty;
  5. proposed support arrangement;
  6. deadline for compliance.

XLIV. Demand Letter Against the Mother

Although many child support demands are addressed to fathers, mothers may also be legally obliged to support their children.

A father, guardian, or custodian may send a demand letter to the mother if she fails to contribute.

Both parents have obligations according to their resources. The law does not make child support exclusively the father’s duty.

XLV. Demand Letter for Shared Expenses

The demand does not always have to be a fixed monthly allowance. It may demand sharing of specific expenses.

For example:

  1. 50% of tuition and school fees;
  2. monthly allowance;
  3. full payment of health insurance;
  4. half of medical expenses;
  5. direct payment of therapy;
  6. direct purchase of medicines;
  7. contribution to rent and utilities;
  8. reimbursement of emergency expenses.

A mixed arrangement may be more practical if the parent doubts how money will be used.

XLVI. Demand Letter for Increase of Support

If the parent already gives support but the amount is insufficient, the letter may demand an increase.

The letter should explain:

  1. current amount of support;
  2. why it is insufficient;
  3. child’s current expenses;
  4. increased school or medical costs;
  5. inflation or changed needs;
  6. requested new amount;
  7. proposed effective date;
  8. deadline to respond.

Example: A parent has been giving ₱5,000 monthly for years, but the child is now in high school and monthly expenses are ₱25,000. The custodial parent may demand an increase based on changed circumstances.

XLVII. Demand Letter for Arrears

If support has not been paid for a period, the letter should include a clear arrears computation.

Example:

  • Agreed support: ₱10,000 per month
  • Last payment: January 2026
  • Unpaid months: February to May 2026
  • Total arrears: ₱40,000

The letter may demand immediate payment of arrears plus continuation of monthly support.

If there was no prior fixed amount, the claimant may compute arrears based on actual expenses and reasonable share.

XLVIII. Demand Letter After Verbal Agreement

Many parents agree verbally on support but never put it in writing. If the supporting parent stops paying, the demand letter should document the prior arrangement.

It may state:

  1. the date or period of the verbal agreement;
  2. amount agreed;
  3. payments previously made;
  4. date payments stopped;
  5. total unpaid amount;
  6. demand for compliance.

Evidence may include bank transfers, text messages, receipts, or admissions.

XLIX. Demand Letter After Annulment, Legal Separation, or Declaration of Nullity

A court decision in an annulment, legal separation, or declaration of nullity case may include provisions on custody and support.

If a parent fails to comply, the demand letter may refer to the court order or judgment.

The remedy may include:

  1. motion for execution;
  2. contempt proceedings;
  3. modification of support;
  4. enforcement of arrears;
  5. protective remedies where applicable.

If no support amount was fixed, a separate request or motion may be needed.

L. Demand Letter Before Filing a VAWC Complaint

Where the mother and child are victims of economic abuse, a demand letter may be used before or alongside a complaint.

However, care must be taken. In situations involving violence, threats, coercive control, or danger, direct communication may be unsafe.

The mother may instead seek assistance from:

  1. barangay VAW desk;
  2. Philippine National Police Women and Children Protection Desk;
  3. prosecutor’s office;
  4. Public Attorney’s Office;
  5. private counsel;
  6. Department of Social Welfare and Development;
  7. local social welfare office.

The demand letter should not delay urgent protection measures when safety is at risk.

LI. Demand Letter for OFW Parent

For an overseas parent, the letter should include practical payment details.

It may request:

  1. remittance to a bank account;
  2. e-wallet transfer;
  3. direct payment to school;
  4. payment of medical insurance;
  5. settlement of arrears by installment;
  6. monthly transfer by a fixed date.

If the OFW parent refuses support, the claimant may explore legal remedies in the Philippines and, in some cases, assistance through agencies handling migrant worker concerns.

LII. Demand Letter When Parent Is Unknown or Cannot Be Located

If the parent’s whereabouts are unknown, a demand letter may be difficult to serve.

The custodial parent may try:

  1. last known address;
  2. email;
  3. social media account;
  4. workplace;
  5. relatives;
  6. registered mail;
  7. barangay assistance;
  8. counsel-assisted tracing;
  9. court action with proper service rules.

If the parent cannot be located, government child welfare remedies or support from other legally obliged relatives may be considered, depending on the circumstances.

LIII. Support From Grandparents or Other Relatives

Parents are primarily obliged to support their children. However, the Family Code also recognizes support obligations among certain relatives, including legitimate ascendants and descendants and, in specific cases, siblings.

A demand against grandparents is more complex and usually arises when parents cannot provide support.

For an illegitimate child, claims against relatives other than the parents may involve limitations depending on legal relationship and classification. The direct claim against the biological parent is usually the primary remedy.

LIV. What Not to Put in the Demand Letter

Avoid including:

  1. threats to post the issue online;
  2. threats to destroy reputation;
  3. insults against the new partner or family;
  4. unsupported accusations;
  5. private sexual details not needed for the claim;
  6. exaggerated amounts without basis;
  7. false statements about income or expenses;
  8. threats of violence;
  9. demands unrelated to the child;
  10. statements that may be interpreted as blackmail.

A demand letter may later be read by a judge, prosecutor, social worker, or opposing counsel. It should be written accordingly.

LV. Sample Structure of a Demand Letter

A demand letter may follow this structure:

  1. heading and date;
  2. recipient’s name and address;
  3. subject line;
  4. introduction identifying the sender and child;
  5. statement of relationship and filiation;
  6. statement of failure or insufficiency of support;
  7. child’s monthly needs and expense summary;
  8. demand for regular support;
  9. demand for arrears or reimbursement, if any;
  10. payment instructions;
  11. deadline for compliance;
  12. warning of legal remedies;
  13. closing and signature;
  14. list of attachments.

LXI. Response to a Demand Letter

The recipient should not ignore a demand letter.

A proper response may:

  1. acknowledge receipt;
  2. admit or clarify filiation;
  3. provide financial information;
  4. propose a reasonable support amount;
  5. ask for receipts or expense breakdown;
  6. offer direct payment of school or medical expenses;
  7. negotiate arrears;
  8. request mediation;
  9. dispute unreasonable claims respectfully;
  10. avoid threats or harassment.

If the recipient genuinely lacks capacity to pay the demanded amount, the response should propose an amount that can be paid regularly rather than giving nothing.

LXII. If the Parent Ignores the Demand Letter

If the parent ignores the letter, possible next steps include:

  1. sending a final demand;
  2. initiating barangay proceedings, if applicable;
  3. filing an action for support;
  4. requesting support pendente lite;
  5. seeking a protection order in economic abuse situations;
  6. filing a criminal complaint where warranted;
  7. seeking assistance from social welfare offices;
  8. enforcing an existing court order;
  9. filing for contempt or execution if there is a judgment;
  10. consulting counsel for the proper remedy.

The best next step depends on the child’s urgency, evidence, relationship of the parties, and whether there are safety concerns.

LXIII. Evidence to Preserve After Sending the Demand Letter

The sender should preserve:

  1. copy of the signed letter;
  2. proof of delivery;
  3. proof of receipt;
  4. replies from the other parent;
  5. screenshots of messages;
  6. proof of partial payments;
  7. proof of refusal;
  8. updated expense receipts;
  9. school assessments;
  10. medical bills;
  11. bank records;

  13. notes of meetings or calls;
  14. barangay records, if any.

These may be important in later proceedings.

LXIV. Legal Risks of False or Exaggerated Claims

The demand letter should be truthful.

False claims may expose the sender to:

  1. loss of credibility;
  2. denial of excessive demands;
  3. counterclaims;
  4. defamation issues;
  5. perjury, if sworn statements are false;
  6. criminal exposure for falsified documents;
  7. adverse findings in custody or support proceedings.

The support amount should be based on reasonable needs and available proof.

LXV. Practical Tips for a Strong Demand Letter

A strong demand letter should:

  1. identify the child clearly;
  2. establish filiation;
  3. describe actual needs;
  4. include a reasonable amount;
  5. attach supporting documents;
  6. give a clear deadline;
  7. provide payment details;
  8. maintain a professional tone;
  9. avoid threats and insults;
  10. preserve proof of receipt;
  11. be consistent with later legal claims.

A demand letter is often more effective when it is specific and evidence-based.

LXVI. Key Takeaways

A demand letter for child support in the Philippines is a formal written request requiring a parent to provide financial support for a child.

The essential points are:

  1. child support is a legal obligation;
  2. both parents may be required to contribute;
  3. legitimate and illegitimate children are entitled to support;
  4. the amount depends on the child’s needs and the parent’s capacity;
  5. the letter should state the facts, amount demanded, deadline, and legal consequences;
  6. proof of filiation is especially important for illegitimate children;
  7. support may include food, housing, clothing, education, medical care, and other necessities;
  8. failure to provide support may lead to civil, criminal, or protective remedies depending on the facts;
  9. a demand letter should be firm, respectful, and well-documented;
  10. the child’s best interest is the controlling consideration.

LXVII. Conclusion

A demand letter for child support is a practical and legally significant tool in the Philippines. It gives the non-supporting parent a clear opportunity to fulfill a legal duty before the dispute escalates. It also creates a record that may later support court action, administrative proceedings, barangay intervention, or protective remedies.

The most effective demand letter is not emotional or threatening. It is factual, organized, and centered on the child. It identifies the child, proves the parent-child relationship, explains the child’s needs, states the amount demanded, gives a deadline, and warns of legal remedies if support is refused.

Child support is not charity, punishment, or payment for access to the child. It is a legal right of the child and a continuing obligation of the parents. In Philippine law, the welfare of the child remains the central concern.
