What Is Heirship Research —
and Why Does It Matter?

Understanding the problem before you commit capital.

When a property owner dies, ownership of their land doesn't simply pass automatically to the next generation. It passes through a legal process — either probate, if there is a will, or intestate succession, if there is not. Until that process is complete and properly recorded, the chain of title to the deceased owner's land may be legally uncertain.

For utility-scale renewable energy developers, this matters enormously. Projects require leases, easements, and access agreements executed by every person with a legal interest in the land. If one of those persons is deceased and their interest hasn't been properly transferred, the document they signed — or should have signed — has a defect. Title companies will not insure around it. Lenders will not close around it.

Heirship research is the process of identifying every legal heir to a deceased landowner's property interest, verifying their identity and legal capacity, and obtaining the documentation needed to resolve title defects that arise from ownership transitions.

When heirship issues appear on projects

• A landowner signed a lease or easement, then died before the project reached financing
• A site control document was executed decades ago; the original signatory is now deceased
• The chain of title shows an ownership transfer through an estate that was never formally probated
• A title search reveals a gap — ownership passes from a deceased person to a current owner with no recorded probate or deed
• A curative instrument requires signatures from heirs of a deceased party

The Legal Framework:
Intestate Succession vs. Probate

Two paths from deceased owner to confirmed heir — and what each requires.

Intestate succession: when there is no will

When a property owner dies without a valid will, their estate passes according to the intestate succession laws of the state where the property is located. Every state has its own statutory scheme — but most follow a hierarchy that prioritizes surviving spouses, then children, then parents, then more distant relatives.

The critical issue for developers: intestate succession creates legal heirs automatically by operation of law — but it does not automatically create a recorded deed or title document. The heirs may own the property, but until someone goes to court, files an affidavit of heirship, or otherwise creates a recorded instrument, the title record is silent on who owns it.

Probate: the court-supervised path

Probate is the court-supervised process of administering a deceased person's estate. It involves proving the validity of a will (if one exists), appointing a personal representative, inventorying assets, paying debts and taxes, and distributing the remaining assets. For real property, probate results in a deed or order of distribution that is recorded in the county deed records — creating a new link in the chain of title.

Affidavits of heirship: the faster alternative

In many states, an affidavit of heirship — a sworn statement by a disinterested witness who knew the deceased and can attest to the identity of their heirs — can be recorded in lieu of formal probate. When properly prepared and recorded, it creates a prima facie record of ownership that title companies will insure over in many circumstances. The threshold for acceptance varies by state, the size of the estate, and the specific facts of the ownership chain.

Step-by-Step:
How to Conduct Heirship Research

A practical framework for identifying heirs on utility-scale projects.

Heirship research is not genealogy research — though genealogy tools are part of the process. The goal is legal sufficiency: identifying every person with a legal claim to the deceased owner's property interest, with enough documentation to support a curative instrument or probate proceeding.

1. Establish the chain of title gap. Pull the full chain of title and identify the deceased owner's name, the date of the last recorded instrument, whether probate was ever opened, and whether any heirs have recorded instruments claiming the property.
2. Obtain the death certificate. Confirms date of death and often provides marital status, state of birth, and next of kin. In most states, death certificates are public records available from the state vital records office.
3. Research marital history. Determine whether the deceased was married at time of death and whether there were prior marriages. In community property states, a surviving spouse may have an ownership interest regardless of how title was held.
4. Identify children and descendants. Under most intestate succession statutes, children are primary heirs — including biological children born outside of marriage, legally adopted children, and descendants of predeceased children under per stirpes distribution.
5. Check for a will or trust. Even if no probate was opened, a will may have been filed with the probate court. A revocable living trust may hold the property and transfer it outside of probate entirely.
6. Search probate court records. Even if the title record shows no probate, check the probate court for the county where the deceased resided and where the property is located. An estate may have been opened without any recorded instrument appearing in the deed index.
7. Document everything. Every step should be documented with source citations. This documentation will be reviewed by your title company and may be examined if the heirship determination is ever challenged.

Curative Instruments:
From Research to Recorded Document

How to convert heirship research into a title-insurable instrument.

Completing heirship research is only half the job. The research has to be converted into a recorded instrument that resolves the title defect. The right instrument depends on the state, the facts, and your title company's requirements.

Affidavit of heirship

A sworn statement executed by two disinterested witnesses who knew the deceased, identifying their heirs and attesting to the relationship. Most title companies will accept it when: the deceased owned the property individually; there is no dispute among potential heirs; and there are no significant creditor claims against the estate.

Muniment of title (Texas and select states)

A will admitted to probate as a muniment of title — a simplified process that establishes the beneficiary's ownership without full estate administration. Only available when the estate has no debts other than those secured by real property.

Small estate affidavit

Most states have a small estate procedure allowing heirs to claim assets without full probate if the estate value is below a statutory threshold. Thresholds vary from $10,000 (Georgia) to $275,000 (Oregon). See the state-by-state table in Chapter 7.

Full probate

When the estate is large, there are disputes among heirs, there are significant debts, or the state doesn't recognize simpler alternatives, full probate is required. A personal representative is appointed, the estate is administered, and a deed or order of distribution is recorded. The most thorough — and most time-consuming — path to a clean title.

Quitclaim deeds from identified heirs

Obtaining quitclaim deeds from all identified heirs, conveying whatever interest they may have to the current owner or project entity. Works best when the number of heirs is manageable and all are cooperative. Does not fully resolve the title gap, but many title companies will accept it in combination with other documentation.

Common Complications —
and How to Navigate Them

The heirship issues that cause the most project delays.

Missing or deceased heirs

Sometimes an heir cannot be located, or an identified heir has also died — creating a second generation of heirship research. A documented diligent search may support a lost heir affidavit or allow the court to appoint a representative to act on behalf of the missing heir's interest.

Disputed heirship

When potential heirs disagree about who is entitled to the property, the dispute may need to be resolved through court proceedings before a curative instrument can be recorded. One of the strongest arguments for identifying heirship issues early — disputes take longer to resolve the closer you are to a closing deadline.

Minor heirs

A minor cannot legally execute a deed or other instrument without court approval. A guardian or conservator must be appointed, and the court must authorize the transaction. This typically takes 60–120 days and adds significant cost.

Trust and entity ownership

When property is held in a trust, the trustee — not the beneficiaries — is the legal owner. Heirship research for trust-held property requires reviewing the trust documents to identify the trustee, beneficiaries, and succession provisions. When property is held by a dissolved corporate entity, additional research traces ownership through the entity's history.

Out-of-state and international heirs

Obtaining signatures from heirs in other states requires coordinating notarization across jurisdictions. Remote notarization is available in most states. Apostilles may be required for instruments executed in foreign countries — adding weeks to the timeline.

Multi-generation undocumented transfers

In some rural areas — particularly Appalachia, the South, and parts of the rural Midwest — informal land transfer across multiple generations has been common. A parcel might show a last recorded deed from the 1940s. Resolving this requires tracing multiple generations of heirship, potentially for five or six deceased owners.

What Lenders and Title Companies Need —
and How to Get Their Buy-In

Meeting the requirements that actually matter at the closing table.

All heirship curative work is ultimately directed toward a single goal: satisfying your project lender and title insurer so the project can close. Understanding what they need — and confirming it before you invest months in research — is essential.

What title companies look for

• A clear, unbroken chain of title from each deceased owner to the current titleholder, with every gap documented
• Curative instruments properly executed, notarized, and recorded in the correct county
• Affidavits of heirship executed by disinterested witnesses with personal knowledge — not family members
• Evidence of diligent search for any missing or unknown heirs
• No open creditor claims or estate debts that could cloud the title

What lenders look for

• Title insurance with specific endorsements covering heirship defects
• Legal opinions from project counsel on the sufficiency of curative work
• Estoppel certificates from current landowners confirming their knowledge of the heirship history
• Extended title searches in states with long recording histories
