In Philippine succession law, the death of a natural person instantly transmits ownership rights over the decedent’s estate to the heirs, even before any formal settlement occurs. An “unsettled estate” is the aggregate of property, rights, and obligations left by the decedent that has not yet been partitioned, distributed, or transferred through extrajudicial or judicial proceedings. This legal reality creates immediate rights and corresponding fiscal responsibilities for heirs, particularly concerning real property taxes imposed by local government units. The interplay between the Civil Code of the Philippines, the Rules of Court, the Local Government Code (Republic Act No. 7160), and the National Internal Revenue Code (as amended) governs these rights and obligations. This article comprehensively examines the legal framework, the nature of heirs’ rights, their authority and duty to pay real property taxes, the procedural aspects of such payments, the consequences of delinquency, and the practical implications in estate administration.

I. Legal Framework: Transmission of Rights Upon Death

The cornerstone provision is Article 777 of the Civil Code, which declares that “the rights to the succession are transmitted from the moment of the death of the decedent.” From that instant, the heirs acquire a direct and immediate title to the hereditary estate, subject only to the payment of the decedent’s debts, taxes, and the legitime of compulsory heirs. This transmission operates by operation of law and does not require probate, court order, or registration to vest ownership.

In intestate succession, which applies in the absence of a valid will or when the will does not dispose of all property, the heirs become co-owners of the entire estate pro indiviso (in undivided shares) under Article 484 of the Civil Code. Each heir holds an ideal or abstract share in every parcel of real property, even though physical division has not yet taken place. Where a will exists and is admitted to probate, the same principle applies to the residuary or intestate portion. Consequently, heirs do not merely have an expectancy; they are already the owners, albeit as co-owners whose rights are held in common until partition.

II. Rights of Heirs in an Unsettled Estate

Because ownership vests immediately, heirs possess the following rights even while the estate remains unsettled:

Right to Possession and Use – Article 493 of the Civil Code grants each co-owner the right to use and enjoy the property in accordance with its intended purpose, without impairing the rights of the others. Heirs may therefore enter, occupy, cultivate, or derive income from real properties forming part of the estate, subject to accounting for fruits received if demanded by co-heirs.
Right to Administer and Manage – In the absence of a court-appointed administrator or executor, any heir or the majority of heirs may assume administration of the estate. This includes the power to collect rents, preserve the property, and make ordinary repairs. Extraordinary acts, such as selling or mortgaging the entire property, generally require the consent of all co-heirs or a court order.
Right to Demand Partition – Under Article 1083 of the Civil Code and Rule 69 of the Rules of Court, any co-heir may compel partition at any time, unless the decedent prohibited it for a period not exceeding twenty years. Partition may be done extrajudicially or judicially.
Right to Alienate or Encumber One’s Share – Each heir may dispose of, mortgage, or encumber his undivided interest (Article 493). However, the buyer or mortgagee acquires only the seller-heir’s share and steps into the co-ownership relationship. Full ownership of specific parcels cannot be transferred without prior settlement and title transfer.
Right to Protect the Estate – Heirs may institute or defend actions concerning the property in their capacity as “heirs of” the decedent. Courts recognize them as real parties in interest even without formal appointment.

These rights exist independently of whether the estate has been settled. Formal settlement merely facilitates the issuance of new titles in the heirs’ names and the orderly distribution of net assets after debts and taxes.

III. Real Property Tax Obligations of Heirs

Real property tax is an annual ad valorem tax levied by provinces, cities, and municipalities under Title II, Chapter III of the Local Government Code (LGC). Section 232 imposes the tax on all real property within the territorial jurisdiction, while Section 199 establishes a tax lien that attaches to the property from the moment the tax becomes due. This lien is superior to all other liens and continues until the tax is paid, regardless of changes in ownership.

Because heirs become owners upon the decedent’s death, they are the “owners” for tax purposes. Tax declarations may remain in the decedent’s name for administrative convenience, but the liability shifts to the heirs. Local treasurers assess and collect the tax based on the latest approved tax declaration, and notices are often sent to the address indicated therein. Heirs who take possession or receive rental income are deemed possessors in the concept of an owner and are solidarily liable for the tax.

The tax liability covers basic real property tax, special levies (e.g., Special Education Fund), and any additional ad valorem taxes authorized by the LGC. Payment is due on or before January 31 of each year, with possible quarterly installments. Failure to pay triggers a 12% per annum interest plus a 25% surcharge under most local tax ordinances.

IV. Authority and Procedures for Heirs to Pay Real Property Taxes

Heirs need not wait for formal estate settlement to discharge real property tax obligations. The following rules apply:

Any Heir May Pay – Because the tax lien burdens the entire property, any co-heir may tender payment to the local treasurer to protect the common interest. The paying heir is entitled to reimbursement from the estate or, after partition, from co-heirs in proportion to their shares. Such payment creates an equitable lien in favor of the paying heir until reimbursed.
Documentary Requirements – Treasurers usually accept payment upon presentation of the death certificate, an affidavit of self-adjudication (if applicable), or a notarized authority from co-heirs. The tax receipt is issued in the name “Heirs of [Decedent],” which preserves the co-ownership status.
No Need for BIR Clearance for RPT Payment – Unlike transfer of title, payment of real property tax does not require prior payment of estate tax or a BIR clearance. However, the estate tax return (BIR Form 1801) must still be filed within one year from death (extendible), and estate tax paid before any transfer of title can be effected.
Updating Tax Declaration – Heirs may request the local assessor to change the tax declaration to “Heirs of [Decedent]” upon submission of the death certificate and an extrajudicial settlement (published if required). This step is advisable for clarity but not mandatory for payment.
Extrajudicial Settlement and Taxes – Under Rule 74 of the Rules of Court, heirs may execute a deed of extrajudicial settlement after six months from the decedent’s death, provided there are no debts and after publication. Payment of current real property taxes is often a precondition for the local treasurer to issue a tax clearance needed for title transfer at the Register of Deeds.

V. Interaction Between Real Property Taxes and Estate Settlement

Estate settlement and real property tax obligations intersect at several points:

Estate Tax First for Title Transfer – Section 91 of the NIRC (as amended by the TRAIN Law) imposes a flat 6% estate tax on the net estate. A Certificate Authorizing Registration from the Bureau of Internal Revenue is required before the Register of Deeds will issue new titles. Real property taxes, however, must be current or settled separately to obtain a tax clearance from the local government.
Deductibility – Real property taxes paid after death but before distribution are deductible from the gross estate as “claims against the estate” if they accrued prior to death, or treated as expenses of administration if incurred thereafter.
Judicial Settlement – When a petition for letters of administration or probate is filed, the appointed administrator must include real property tax liabilities in the inventory and may pay them from estate funds. Heirs retain the right to advance payments and seek reimbursement.

VI. Consequences of Non-Payment and Available Remedies

Non-payment of real property taxes exposes the property to delinquency proceedings:

Auction Sale – After due notice and publication, the local treasurer may sell the property at public auction. The winning bidder acquires the property subject to the one-year redemption period granted to the “owner” or “person having legal interest” (Section 260, LGC).
Redemption Rights of Heirs – Heirs, as persons with legal interest, may redeem the property within one year from the date of sale by paying the amount of the delinquent tax, interest, surcharge, and penalties. Redemption restores the property to the co-ownership of the heirs.
Prescription – The tax lien itself does not prescribe while the property remains with the heirs. However, once sold at auction and not redeemed, the government’s title becomes indefeasible.
Personal Liability – While the primary recourse is against the property, local governments may also pursue collection against any heir in possession or who received fruits, though solidary liability is limited to the value of the inheritance received.

VII. Practical Considerations and Best Practices

Heirs should promptly inventory all real properties and ascertain outstanding real property taxes. Maintaining payment records is essential for accounting during partition. Paying taxes demonstrates good faith and strengthens a paying heir’s position in any reimbursement or contribution claim. Where multiple heirs exist, a written agreement designating one heir as tax custodian is advisable.

In cases involving minors or incapacitated heirs, court approval may be required for certain acts. Foreign heirs must comply with the Foreign Ownership restrictions under the Constitution when ultimately partitioning or selling.

The rights of heirs to an unsettled estate are robust and immediate, yet they carry the correlative duty to preserve the property through timely payment of real property taxes. By exercising their ownership rights responsibly—paying taxes, protecting the common interest, and moving toward orderly settlement—heirs fulfill both their legal obligations and the decedent’s presumed intent to transmit an unencumbered patrimony. Philippine law balances these rights and duties to ensure that the transmission of wealth is not frustrated by fiscal neglect or protracted litigation.
