A deal dies from not verifying a seller's legal capacity

A deal dies from not verifying a seller's legal capacity when the person signing the contract doesn't actually have the authority to sell the property. This often happens with inherited properties, trusts, or power of attorney situations.

What "legal capacity" means for sellers

Legal capacity means the seller has the legal right and mental competence to enter into a binding contract and transfer property ownership. Without it, your contract is essentially invalid.

This involves confirming he or she is the rightful owner, is of sound mind, and is not under duress. It also means if he or she is acting on behalf of another, he or she has the proper legal documentation to do so.

This is not legal advice. Always consult with a legal professional for specific situations.

Common situations where capacity is an issue

Inherited properties are a prime example. You might speak to an heir, but if there are multiple heirs or the estate hasn't gone through probate, that single heir cannot legally sell the property alone.

Properties held in a trust also pose a challenge. The individual you are speaking with might be a trustee, but you need to verify the trust documents to ensure he or she has the authority to sell. The trustee is not the owner, the trust is.

Power of attorney situations require careful vetting. You need to see the actual power of attorney document to confirm it is valid, properly executed, and grants the agent the power to sell real estate.

The habit: always ask about ownership and authority

Make it a standard part of your initial conversation to ask directly: "Who exactly is on the deed for this property?" and "Are there any other parties involved in the decision to sell, like family members, trusts, or an estate?"

This habit helps you uncover potential issues early. If the seller is vague or hesitant, that's a red flag you need to investigate further. For tips on first calls, see /learn/first-call-with-a-motivated-seller.

Don't assume the person you are talking to is the sole decision maker or has full authority. Many deals die because investors assume this and then find out later that key parties were missing.

Documents to request and review

If the property is inherited, ask for a death certificate and proof of heirship, or details about the probate process. You will want to see letters testamentary or letters of administration from the court.

For properties in a trust, request a copy of the trust agreement or at least the relevant sections that grant the trustee the power to sell real estate. For properties with multiple owners, ensure all owners are on board.

When a power of attorney is involved, ask for the original document. Verify that it's current and specifically grants the authority to sell real property. Never proceed without seeing these documents yourself.

When to involve a title company or attorney early

If you uncover any complexity regarding ownership or legal capacity, bring your title company or real estate attorney into the loop immediately. They can perform a preliminary title search and advise on necessary documentation.

Their expertise can confirm the true ownership and legal authority much faster and more reliably than you trying to piece it together yourself. This can save you significant time and prevent a deal from collapsing later.

It's an investment in due diligence that protects your time and capital. For more on working leads, see /how-to-work-your-leads.

Questions people ask

What if the seller says he or she is the sole owner?

Always verify with public records or a preliminary title search. While a seller might genuinely believe he or she is the sole owner, there could be unrecorded claims, liens, or other heirs not immediately apparent.

Should I ask for a death certificate?

Yes, if the property is inherited, requesting a death certificate and details about the probate process is a standard part of due diligence. You need to ensure the estate is properly settled and the person you're dealing with has authority.

Do I need to check probate records myself?

You can, but it's more efficient to have your title company or attorney do this. They have access to the necessary databases and expertise to interpret the records, confirming the legal standing of the estate and heirs.
