I. Introduction

Co-ownership of real property is common in the Philippines. It arises among heirs before partition of an estate, spouses or former spouses holding property together, siblings who inherited ancestral land, business partners who bought property jointly, or persons who acquired undivided shares in the same parcel of land.

A recurring problem in co-ownership is the payment of real property tax. One co-owner may pay the entire delinquent tax to prevent penalties, levy, auction, or forfeiture. The question then follows: May that paying co-owner recover from the other co-owners their proportionate shares?

In Philippine law, the answer is generally yes, subject to proof, proportionate ownership, prescription, and defenses. Real property taxes are charges on the property. As between co-owners, however, each co-owner should bear the expenses necessary for the preservation and enjoyment of the common property in proportion to his or her share.

This article discusses the legal basis, remedies, procedure, evidence, defenses, and practical considerations in recovering a co-owner’s share in unpaid or advanced real property taxes in the Philippine setting.

II. Nature of Co-Ownership

Co-ownership exists when the ownership of an undivided thing or right belongs to different persons.

In co-ownership, each co-owner owns an ideal or undivided share in the whole property. A co-owner does not own a physically identified portion unless there has already been partition. Thus, a co-owner with a one-fourth share does not necessarily own the front one-fourth, rear one-fourth, or any specific portion. Instead, that co-owner owns one-fourth of the entire property in an abstract legal sense.

Because all co-owners benefit from the preservation of the property, the expenses necessary to preserve the property should generally be shared.

Real property tax is one such expense.

III. Real Property Tax as an Expense of Preservation

Real property tax is imposed by local government units on real property, including land, buildings, machinery, and improvements. It is a recurring public charge attached to the ownership or beneficial use of real property.

Failure to pay real property tax may result in:

Accrual of interest and penalties;
Issuance of notice of delinquency;
Levy on the property;
Public auction sale;
Loss of the property if not redeemed within the legal redemption period; and
Practical difficulty in sale, transfer, partition, or settlement of the property.

For this reason, payment of real property tax is not merely voluntary generosity. It is a necessary act to protect the property from legal and financial consequences. A co-owner who pays the whole tax prevents prejudice not only to himself but also to the other co-owners.

IV. Legal Basis for Recovery

A. Civil Code Rule on Necessary Expenses

Under the Civil Code principles on co-ownership, each co-owner has a right to compel the others to contribute to the expenses of preservation of the thing or right owned in common.

Real property taxes, especially delinquent taxes needed to avoid penalties, levy, or auction, are properly treated as expenses for the preservation of the co-owned property.

Therefore, if one co-owner pays the full real property tax, that co-owner may demand reimbursement from the others in proportion to their respective shares.

B. Benefit to the Common Property

The basis of recovery is not merely the payment itself. The stronger reason is that the payment benefits all co-owners by preserving the property.

If the paying co-owner shoulders the entire tax and the others refuse to contribute, the non-paying co-owners are unjustly enriched. They keep their ownership interests protected while avoiding their corresponding burden.

C. Quasi-Contract or Unjust Enrichment

Recovery may also be supported by the concept of quasi-contract or unjust enrichment. When a person benefits at the expense of another without just or legal ground, the law may require restitution.

In the context of co-owned property, a non-paying co-owner benefits when another co-owner pays taxes that protect the whole property. Unless there is a valid agreement that the paying co-owner will shoulder all taxes, the non-paying co-owner should reimburse the proportionate share.

D. Payment by a Person Interested in the Obligation

A co-owner who pays real property tax is not a stranger to the obligation. That co-owner has a direct interest in preventing the property from becoming delinquent or being sold at auction. The payment is made to protect a real property interest. This supports the right to seek contribution from the others.

V. Who May Recover?

The person who may recover is usually the co-owner who paid more than his or her proportionate share of the real property tax.

The claimant may be:

A registered co-owner appearing on the certificate of title;
An heir who is a co-owner of inherited property before partition;
A buyer of an undivided share;
A spouse, former spouse, or partner who co-owns the property;
A judicial or extrajudicial administrator who advanced payment using personal funds;
A co-owner in possession who paid taxes for the entire property; or
A successor-in-interest who paid delinquent taxes to protect the property.

The key requirement is that the claimant must prove both co-ownership and payment.

VI. From Whom May Recovery Be Sought?

Recovery may be sought from the other co-owners who benefited from the payment.

If the property is inherited and still undivided, the action may be brought against the other heirs or successors who own shares in the estate property.

If a co-owner has sold or transferred his undivided share, the timing matters. Taxes that accrued while the transferor was still a co-owner may generally be charged to the transferor, unless the parties agreed otherwise. Taxes accruing after transfer may be chargeable to the transferee as the new owner or beneficial holder of the share.

If a co-owner is deceased, the claim may have to be presented against the estate, depending on the circumstances and procedural posture.

VII. How Much May Be Recovered?

The general rule is proportionate sharing according to ownership interest.

For example:

A, B, C, and D co-own land equally.
The total real property tax and penalties paid by A amount to ₱100,000.
Each co-owner’s share is 25%.
A’s own share is ₱25,000.
A may recover ₱25,000 each from B, C, and D, or a total of ₱75,000.

If the co-ownership shares are unequal, reimbursement follows the actual shares.

For example:

A owns 50%.
B owns 25%.
C owns 25%.
A paid ₱120,000 in real property taxes.
A’s own share is ₱60,000.
B should reimburse ₱30,000.
C should reimburse ₱30,000.

The paying co-owner cannot recover the portion corresponding to his own share because he was already legally bound to shoulder that portion.

VIII. What Amounts Are Recoverable?

The recoverable amount may include:

Basic real property tax;
Special Education Fund tax, where applicable;
Penalties and interest paid due to delinquency;
Other lawful charges imposed by the local treasurer in connection with the tax delinquency;
Documentary expenses directly related to proving payment, in proper cases; and
Legal interest, if awarded by the court.

However, the claimant should distinguish between necessary tax payments and optional or personal expenses.

Not every expense connected to the property is automatically reimbursable. The expense must be shown to be necessary, beneficial to the co-owned property, or authorized by agreement or law.

IX. Are Penalties and Interest Recoverable?

Generally, yes, if the penalties and interest were part of the delinquent real property tax paid to preserve the property.

However, disputes may arise when the paying co-owner’s own delay caused the penalties to accumulate. The other co-owners may argue that they should not bear penalties caused solely by the claimant’s negligence or unilateral delay.

The fair approach depends on the facts:

If all co-owners knew of the delinquency and failed to contribute, penalties may be shared.
If one co-owner was managing the property and failed to pay on time despite having funds or authority, that co-owner may have difficulty charging all penalties to the others.
If the claimant paid only after years of inaction but all co-owners equally neglected the obligation, proportional sharing may still be proper.
If there was an agreement that one co-owner would handle taxes from rents or income, accountability may be adjusted based on that agreement.

X. Effect of Exclusive Possession by One Co-Owner

A common defense is that the paying co-owner exclusively possessed, used, leased, or benefited from the property. The non-paying co-owner may argue that the taxes should be borne by the co-owner who enjoyed the property.

Exclusive possession does not automatically defeat the claim for reimbursement. But it may affect accounting.

If one co-owner exclusively used the property and excluded the others, the excluded co-owners may counterclaim for their share in the reasonable rental value, fruits, or income. In that situation, the court may offset the tax reimbursement claim against the value of exclusive use.

For example:

A paid ₱80,000 in real property taxes.
B’s share is ₱40,000.
But A exclusively leased the property and collected rent without giving B any share.
B may claim that A must account for B’s share in the rentals.
The court may order an accounting and offset the amounts.

Thus, tax reimbursement claims often overlap with broader co-ownership disputes involving possession, rentals, fruits, improvements, and partition.

XI. Effect of Rental Income from the Property

If the co-owned property produces income, such as rent, the proper source for paying taxes may be the income of the property itself.

A co-owner who collects rent from the common property may be required to account to the others. Real property taxes may be deducted as necessary expenses before net income is distributed.

For example:

The co-owned property earns ₱300,000 in annual rent.
Real property tax is ₱30,000.
Necessary repairs are ₱20,000.
Net income is ₱250,000.
The net income should be divided according to ownership shares.

A co-owner who collected rents but failed to pay taxes cannot simply demand contribution without accounting for the income received.

XII. Effect of Tax Declaration in One Name Only

In many Philippine properties, especially inherited land, the tax declaration may be in the name of only one ancestor, heir, or possessor. This does not necessarily mean that only that person owns the property.

A tax declaration is evidence of a claim of ownership or possession, but it is not conclusive proof of ownership. Ownership is determined by title, succession, deeds, partition documents, judgments, or other competent evidence.

Thus, even if the real property tax receipt is in the name of only one co-owner, the payment may still benefit all co-owners if the property is in fact co-owned.

Conversely, a person cannot recover from alleged co-owners merely by showing tax receipts. The claimant must prove that the persons sued are indeed co-owners or otherwise liable to contribute.

XIII. Effect of Torrens Title

If the property is covered by a Torrens title showing several registered owners, the ownership shares may be stated on the title or may be presumed equal if no different proportion appears and no contrary evidence is presented.

If the title is still in the name of a deceased person, the heirs may be co-owners by succession before partition. In that case, the claimant must prove the relationship, succession, and respective hereditary shares.

If the title shows only one owner, a person claiming co-ownership must first establish the basis of co-ownership before demanding contribution.

XIV. Co-Ownership Among Heirs

The issue commonly arises in estates.

Upon death, the heirs acquire rights to the estate subject to settlement of debts, taxes, and administration. Before partition, heirs are generally co-owners of hereditary property. If one heir pays real property taxes on inherited land, that heir may recover proportionate reimbursement from the other heirs, assuming the payment benefited the estate property.

However, hereditary shares must be carefully determined. Shares may vary depending on:

Whether the decedent left a will;
Whether there are compulsory heirs;
Whether the surviving spouse is involved;
Whether the property was conjugal, community, exclusive, or paraphernal;
Whether representation applies;
Whether there were prior donations or advances;
Whether there has been extrajudicial settlement or partition; and
Whether some heirs sold or waived their shares.

A reimbursement claim among heirs may therefore require estate accounting or partition.

XV. Can a Co-Owner Refuse to Contribute by Renouncing His Share?

Under Civil Code principles, a co-owner may be exempted from contributing to expenses for preservation by renouncing so much of his undivided interest as may be equivalent to his share of the expenses. This is not a casual verbal refusal. It involves relinquishment of a corresponding property interest.

In practice, this is rarely used because a co-owner usually does not want to give up part of the ownership interest merely to avoid reimbursing taxes.

A mere statement such as “I do not want to pay” or “I am not using the property” is not equivalent to a valid renunciation of the required share.

XVI. Demand Before Suit

Before filing a court case, the paying co-owner should ordinarily make a written demand.

The demand letter should state:

The identity and description of the property;
The basis of co-ownership;
The total real property tax paid;
The date and place of payment;
The period covered by the tax payment;
The co-owner’s share in the property;
The amount being demanded;
A request for payment within a definite period; and
A statement that legal action may be taken if payment is not made.

A written demand is important because it establishes that the other co-owner was asked to pay and refused or failed to do so. It may also be relevant to the accrual of interest, attorney’s fees, and proof of good faith.

XVII. Evidence Needed to Recover

A claimant should prepare the following evidence:

Certified true copy of the transfer certificate of title, original certificate of title, condominium certificate of title, or other title document;
Tax declaration;
Real property tax receipts;
Statement of account from the city or municipal treasurer;
Certificate of real property tax payment or tax clearance;
Computation of delinquency, penalties, and interest;
Proof of payment source, such as official receipts, bank records, manager’s checks, or online payment confirmations;
Documents proving co-ownership, such as deeds, inheritance documents, extrajudicial settlement, birth certificates, marriage certificates, death certificates, or court orders;
Written demands sent to the co-owners;
Proof of receipt of demand letters;
Communications admitting liability or acknowledging co-ownership;
Records of rental income or property expenses, if relevant; and
Any agreement among co-owners regarding payment of taxes.

The claimant must be ready to prove both the amount paid and the defendant’s proportionate liability.

XVIII. Causes of Action

Depending on the facts, the paying co-owner may frame the action as one or more of the following:

A. Action for Sum of Money

This is the most direct remedy. The paying co-owner sues the non-paying co-owner for the amount corresponding to the latter’s share in the real property taxes paid.

B. Action for Reimbursement or Contribution

The claim may be described as one for reimbursement or contribution among co-owners for necessary expenses.

C. Accounting

If the property produced income or one co-owner possessed or leased the property, an accounting may be necessary. The court may determine taxes, income, repairs, improvements, and net shares.

D. Partition with Accounting

If the co-ownership is no longer workable, a co-owner may seek partition. In a partition case, the court may also settle reimbursements, taxes, expenses, fruits, rents, and charges affecting the common property.

E. Set-Off or Counterclaim

If sued for reimbursement, a co-owner may counterclaim for rentals, fruits, unauthorized use, damages, or other amounts owed by the claimant.

XIX. Venue and Jurisdiction

The proper forum depends on the nature and amount of the claim.

If the action is purely for a sum of money, jurisdiction will depend on the amount demanded, exclusive of interest, damages, attorney’s fees, litigation expenses, and costs, unless these are specifically part of the principal claim under applicable procedural rules.

If the action involves title to or possession of real property, partition, or interests in real property, it may fall under the jurisdictional rules for real actions.

Venue also depends on whether the action is personal or real. A simple reimbursement claim may be personal, while partition or recovery of real property is real and should be filed where the property is located.

Because jurisdictional thresholds and procedural rules can change, a litigant should verify the current rules before filing.

XX. Barangay Conciliation

If the parties are individuals residing in the same city or municipality, or in adjoining barangays within the same city or municipality, barangay conciliation may be required before filing in court, subject to exceptions.

Many disputes among relatives and co-owners must first pass through the Katarungang Pambarangay process. Failure to comply, when required, may result in dismissal or delay.

However, barangay conciliation may not be required in certain cases, such as where one party is a juridical entity, where parties reside in different cities or municipalities that are not covered by the rule, where urgent legal action is necessary, or where the dispute falls within recognized exceptions.

XXI. Prescription

Prescription is a critical issue.

The period to file depends on how the claim is characterized:

If based on a written agreement among co-owners, a longer prescriptive period for written obligations may apply.
If based on an implied obligation, quasi-contract, or reimbursement, a different period may apply.
If included in an action for partition and accounting, additional considerations may apply because co-ownership itself may continue until partition, but money claims may still be affected by laches or prescription.
If there were repeated payments over many years, each payment may have its own reckoning point.

A paying co-owner should not wait too long. Even if co-ownership continues, the right to recover specific tax advances may be challenged if stale.

XXII. Legal Interest

The paying co-owner may ask for legal interest on the amount due.

Legal interest is not automatic in every case. It depends on demand, the nature of the obligation, judicial determination, and the court’s ruling.

As a practical matter, the demand letter should clearly specify the amount claimed and request payment by a definite date. This helps establish delay.

XXIII. Attorney’s Fees and Litigation Expenses

Attorney’s fees may be claimed but are not awarded as a matter of course. Courts generally require a legal and factual basis, such as bad faith, unjustified refusal to pay, or circumstances recognized by law.

A clause in a written agreement among co-owners may also provide for attorney’s fees, but the court may still reduce unreasonable amounts.

XXIV. Defenses of the Non-Paying Co-Owner

A defendant co-owner may raise several defenses:

A. No Co-Ownership

The defendant may deny being a co-owner or deny the claimant’s alleged share.

B. Wrong Share Computation

The defendant may admit co-ownership but dispute the percentage used in computing liability.

C. Payment Already Made

The defendant may prove that he already contributed, either directly to the local treasurer or to the claimant.

D. Property Income Should Have Paid the Taxes

If the property generated rent or income, the defendant may argue that the taxes should have been paid from common income already collected by the claimant.

E. Exclusive Possession by Claimant

The defendant may argue that the claimant exclusively used the property and should account for rental value or fruits.

F. Voluntary Payment Without Authority

The defendant may argue that the payment was unnecessary, excessive, unauthorized, or not actually for the common property.

This defense is weaker when the payment was for lawful real property taxes necessary to avoid delinquency consequences.

G. Prescription or Laches

The defendant may argue that the claim was filed too late.

H. Waiver, Agreement, or Settlement

The defendant may show that the parties had agreed that the claimant would shoulder taxes, perhaps in exchange for use, possession, rental income, or another benefit.

I. Invalid or Unsupported Receipts

The defendant may challenge whether the receipts correspond to the property, period, or amount being claimed.

XXV. Distinction Between Tax Liability to the Government and Reimbursement Among Co-Owners

It is important to distinguish two relationships:

The relationship between the taxpayer/property and the local government; and
The relationship among co-owners.

For real property tax purposes, the local government may enforce the tax against the property through statutory remedies. The tax is a charge on the property.

But as between co-owners, the issue is equitable and civil: who should ultimately bear the burden?

Thus, even if the local government accepted full payment from one co-owner, that does not mean the paying co-owner alone should bear the entire tax. The payment settles the government’s claim, but it does not automatically settle the private reimbursement rights among co-owners.

XXVI. Can the Paying Co-Owner Acquire Ownership by Paying Taxes?

Payment of real property taxes alone does not automatically make the paying co-owner the sole owner of the property.

This is a common misconception. Tax payments may be evidence of a claim of ownership, possession, or administration, but they do not by themselves transfer title or extinguish the shares of other co-owners.

A co-owner cannot simply pay taxes and declare that the other co-owners have lost their shares. Transfer of ownership requires a valid legal mode, such as sale, donation, succession, partition, consolidation after tax sale and failure of redemption, or court judgment.

However, long-term exclusive possession, tax declarations, tax payments, and acts adverse to the other co-owners may become relevant in exceptional cases involving prescription, repudiation of co-ownership, or adverse possession. Such cases require strict proof because possession by one co-owner is generally presumed to be possession for all unless there is clear repudiation brought to the knowledge of the others.

XXVII. Tax Sale and Redemption Issues

If real property taxes remain unpaid, the local government may levy and sell the property at public auction. If one co-owner pays the delinquent taxes before auction, the reimbursement issue is straightforward.

If one co-owner redeems the property after tax sale, the redeeming co-owner may likewise seek contribution because redemption preserves the property.

If one co-owner buys the property at a tax sale, more complicated issues arise. A co-owner purchasing the common property at a tax delinquency sale may be deemed, in equity, to have acted for the benefit of the co-ownership, especially if the purchase was made using the tax default affecting the common property. Courts may scrutinize such transactions because a co-owner should not unfairly profit from a tax delinquency to defeat the shares of the others.

The safer rule is that a co-owner who pays taxes, redeems, or otherwise protects the property should seek reimbursement rather than attempt to appropriate the shares of the others.

XXVIII. Improvements Distinguished from Taxes

Taxes should be distinguished from improvements.

Real property taxes are generally necessary charges for preserving the property from government enforcement.

Improvements, however, may be:

Necessary;
Useful;
Luxurious;
Authorized;
Unauthorized; or
Made for the sole benefit of one co-owner.

A co-owner who builds a structure, renovates, fences, or develops the property without consent may not always recover proportionate reimbursement in the same way as tax payments. The rules on improvements are more fact-sensitive.

Taxes are easier to justify as reimbursable because they are imposed by law and protect the property itself.

XXIX. Practical Steps Before Filing a Case

A paying co-owner should consider the following steps:

Secure certified copies of tax receipts and tax clearances.
Obtain the latest title and tax declaration.
Determine the exact ownership shares.
Prepare a table of payments by year, quarter, amount, penalty, and receipt number.
Compute each co-owner’s share.
Check whether the property generated income.
Review any written or verbal agreement among co-owners.
Send a written demand.
Attempt settlement or mediation.
Consider barangay conciliation if required.
File the proper action only if settlement fails.

A well-documented reimbursement claim is often easier to settle.

XXX. Sample Computation

Assume the following:

Property is co-owned by five siblings equally.
One sibling paid delinquent real property taxes of ₱250,000.
Each sibling owns 20%.
Paying sibling’s own share is ₱50,000.
Each of the four other siblings owes ₱50,000.

Computation:

Co-Owner	Share	Share in Tax	Amount Recoverable by Paying Co-Owner
A, paying co-owner	20%	₱50,000	Not recoverable
B	20%	₱50,000	₱50,000
C	20%	₱50,000	₱50,000
D	20%	₱50,000	₱50,000
E	20%	₱50,000	₱50,000

Total recoverable by A: ₱200,000.

If one sibling owns a different share, the computation must be adjusted.

XXXI. Sample Demand Letter

Subject: Demand for Reimbursement of Proportionate Share in Real Property Taxes

Dear __________:

I write regarding the real property located at __________, covered by Tax Declaration No. __________ and/or Title No. __________, which is co-owned by us in the following shares: __________.

To prevent further delinquency, penalties, and possible enforcement proceedings against the property, I paid the real property taxes due on the property for the period __________ in the total amount of ₱__________. Copies of the official receipts and related tax documents are attached.

Based on your ownership share of , your proportionate share in the amount paid is ₱.

Please pay said amount within __________ days from receipt of this letter. If payment has already been made, kindly provide proof so that our records may be reconciled.

This demand is made without prejudice to all rights and remedies available under law, including the recovery of legal interest, attorney’s fees, and costs, if warranted.

Sincerely,

XXXII. Settlement Options

Co-owners may avoid litigation by agreeing on practical arrangements, such as:

Equal or proportional reimbursement;
Installment payment;
Deduction from future rental shares;
Offset against other expenses or benefits;
Sale of the property and deduction of taxes from proceeds;
Partition, with tax advances considered in the accounting;
Appointment of one co-owner as administrator;
Opening a common bank account for property expenses;
Annual contribution schedule; or
Written co-ownership agreement.

A written agreement is highly advisable, especially for inherited property.

XXXIII. Preventive Measures

To avoid repeated disputes, co-owners should establish a clear system for property expenses.

A co-ownership agreement may cover:

Who will monitor tax deadlines;
How much each co-owner must contribute;
When contributions are due;
Where payments will be deposited;
Who will keep receipts;
Whether penalties caused by delay will be shared or charged to the delaying co-owner;
How rental income will be collected and distributed;
How repairs and improvements will be approved;
Whether a co-owner in exclusive possession must pay rent or shoulder taxes;
How disputes will be resolved; and
Whether the property should eventually be sold or partitioned.

The lack of a written agreement is one of the main reasons family co-ownership disputes escalate.

XXXIV. Relationship to Partition

A co-owner is generally not required to remain in co-ownership indefinitely. Any co-owner may demand partition, subject to legal limitations and valid agreements.

If unpaid taxes and reimbursement disputes have accumulated, partition may be the most complete remedy. In partition, the court may determine the shares of the parties, order physical division if feasible, order sale if division is impracticable, and settle accounting matters.

Tax advances by one co-owner may be credited in the accounting before distribution of the property or sale proceeds.

For example, if the property is sold, the court or parties may agree that the paying co-owner will first be reimbursed from the proceeds for tax payments exceeding his share, before the balance is divided.

XXXV. Special Issues in Family Properties

Family properties often involve informal arrangements. One sibling may live on the land, another may pay taxes, another may keep the title, and others may be abroad. These arrangements can create misunderstandings.

Common issues include:

One heir pays taxes for decades and later claims sole ownership;
Other heirs refuse to reimburse because they never used the property;
A sibling in possession collects rent but asks others to share taxes;
Tax declarations are transferred to one heir’s name without partition;
Some heirs are unaware of tax delinquencies;
Property is nearly auctioned before one heir pays everything;
Receipts are lost;
Shares are unclear because the estate was never settled; and
Heirs of deceased heirs enter the picture.

The legal solution usually requires proof of ownership, proof of payment, accounting, and sometimes partition or estate settlement.

XXXVI. Important Limitations

A reimbursement claim may fail or be reduced if:

The claimant cannot prove co-ownership;
The claimant cannot prove actual payment;
The receipts refer to a different property;
The claimant used common funds but claims personal reimbursement;
The property income was sufficient to cover taxes;
The claimant had agreed to shoulder taxes in exchange for exclusive use;
The claim is prescribed;
The computation is wrong;
The defendant had already paid;
The payment was not necessary or was excessive;
The claimant is also liable to account for fruits or rentals; or
The claim is procedurally defective.

XXXVII. Legal Character of the Claim

A claim for recovery of a co-owner’s share in real property taxes is usually a personal money claim arising from co-ownership. It does not necessarily involve ownership transfer.

However, when the claim is joined with partition, accounting, possession, or title issues, it may become part of a broader real property dispute.

The pleadings should therefore be carefully framed. A complaint that merely seeks reimbursement should not unnecessarily raise title issues unless ownership is disputed. Conversely, if the parties dispute shares or inheritance rights, a simple collection case may be insufficient.

XXXVIII. Burden of Proof

The paying co-owner has the burden to prove:

The existence of co-ownership;
The defendant’s share;
The tax obligation or delinquency;
Actual payment;
That the payment benefited the common property;
The amount corresponding to the defendant’s share;
Demand, if relevant; and
Non-payment by the defendant.

The defendant has the burden to prove affirmative defenses such as payment, waiver, prescription, agreement, offset, exclusive use, or lack of benefit.

XXXIX. Recommended Pleading Allegations

A complaint for reimbursement should clearly allege:

The parties and their addresses;
The property description;
The basis of co-ownership;
The respective shares;
The tax delinquency or tax obligation;
The claimant’s payment;
The official receipts and periods covered;
The defendant’s proportionate share;
Demand and refusal or failure to pay;
The legal basis for reimbursement;
Claim for interest, attorney’s fees, and costs, if justified; and
The specific relief prayed for.

A vague complaint may invite dismissal, delay, or unnecessary factual disputes.

XL. Conclusion

In Philippine law, a co-owner who pays real property taxes for the entire co-owned property may generally recover from the other co-owners their proportionate shares. The reason is simple: real property taxes are necessary charges that preserve the property, and all co-owners benefit from their payment.

The right to recover is strongest when the claimant can prove co-ownership, actual payment, correct computation, prior demand, and absence of any agreement shifting the tax burden solely to the claimant.

However, the claim may be complicated by exclusive possession, rental income, inheritance issues, prescription, prior agreements, or the need for accounting and partition. For this reason, the paying co-owner should keep complete records, make a written demand, attempt settlement, and choose the correct legal remedy.

The central principle remains: the burden of preserving co-owned property should be borne by all co-owners according to their respective shares, unless a valid agreement or legal reason provides otherwise.
