My mother-in-law stopped paying her share of our $660,000 house. What now?

The question

An illustrative letter.

The answer

My dear, what a hard place to stand. You built a home for three generations, you lost your father-in-law, and now the arrangement that held it together is coming apart while everyone is still grieving. I spent many years in mortgage lending, and I watched family homes like yours go well and go badly. The difference, almost always, was what got written down and how early. You can still write it down. Let us start there.

Who does the lender expect to pay?

The lender does not know about your family's arrangement and does not care how you split the bill. If you and your husband signed the mortgage, the lender expects the full payment from you each month, whatever anyone else promised. If your in-laws signed it too, each borrower is usually responsible for the whole amount, not just a share. A payment that falls 30 days behind can be reported on the credit of everyone on the loan.

So the first job is to keep the mortgage current while the family sorts out the rest. If that means covering her $3,600 for a few months from savings, it is usually worth it. Late payments and a damaged credit record would make every option that follows harder. Keep a careful record of every dollar you pay on her behalf. It may matter later.

Who owns the house now?

This is the question many families skip, and it shapes everything. Find the deed and look at how the four of you took title. If it says joint tenants with right of survivorship, your father-in-law's share likely passed to the surviving owners automatically. If you hold it as tenants in common, his share passed under his will, or under Texas inheritance law if he had none, and Texas community property rules can affect who received it. Your husband may own more of the house than he realizes, or other heirs may own part of it now.

A Texas real estate attorney can read the deed and any will with you in a single meeting. That is money well spent before any family conversation about numbers.

Are those texts worth anything?

They are worth keeping. Messages that show what each person agreed to pay, and that everyone acted on that agreement for years, help explain the deal to a lawyer, a mediator or, if it came to it, a judge. But they are a record of good intentions, not a full contract. They probably say nothing about what happens if someone dies, remarries, wants to move or stops paying, and that gap is why you are here. Save them, back them up, and stop relying on them.

What are our options?

Most families in your position end up with one of these:

• A new written agreement. She stays and pays a smaller, fixed amount, perhaps as rent for her rooms rather than as an owner. It is signed, and it covers what happens if circumstances change again.
• A buyout. You and your husband buy her share. That usually means refinancing into your names alone, which removes her from the loan and requires that you qualify for the full payment.
• She moves on with her share. If she wants a new start, her part of the equity could help her buy or rent something smaller, once a buyout figure is agreed.
• A sale. Everyone takes their share of the equity and starts fresh. It is the cleanest break, though selling and moving are costly and painful.
• A court-ordered division. In Texas, as in most states, any co-owner can ask a court to divide or sell jointly owned property, which is called a partition. It is slow and expensive, and it is the last resort, not the first.

How do we have the conversation?

Let your husband lead. She is his mother, and she is grieving, perhaps more than she shows. A new relationship does not mean she has stopped missing her husband. She may also be frightened about money now that his income is gone. Begin with that, not with the $3,600: "Mom, we want you to be all right. We also need the house to work for all of us. Let's find a plan together."

If every conversation turns into an argument, bring in someone neutral. Many Texas counties have dispute resolution centers that offer mediation at modest cost, and a mediator can help a family reach terms that a lawyer then puts in writing.

What should we do this month?

• Keep paying the full mortgage on time.
• Record every payment you make toward her share.
• Find the deed, the closing papers and any will.
• Book one meeting with a Texas real estate attorney.
• Then sit down as a family, with your husband leading.

My dear, family homes can be beautiful things. They can also become the place where love and money tangle so tightly that no one can breathe. Writing things down does not mean you distrust each other. It means you care enough to protect each other when life changes, as it always does.

One thing to do this week

Find the deed and closing papers, and book one meeting with a Texas real estate attorney before the family talk.
