In Texas, whether or not you need to probate a will to sell a home as the spouse depends on several factors:

1. Community Property with Right of Survivorship:
   If the property was owned as community property with the right of survivorship, it may automatically transfer to the surviving spouse without requiring probate. The deed would need to specify this arrangement.

2. Sole Ownership or Tenants in Common:
   If the property was solely in the deceased spouse's name or owned as tenants in common, the property becomes part of the deceased's estate. In this case, probate may be necessary to establish your legal authority to sell the property.

3. Heirship Affidavit:
   If there is no will, or the will wasn't probated, you might be able to file an affidavit of heirship to establish ownership. This is typically used when no formal probate is planned and can be recorded in the county where the property is located.

4. Will Exists but No Probate:
   If a valid will exists and names you as the sole heir, the will typically must be probated to establish your legal right to sell the property.

5. Title Company Requirements:
   Most title companies will require proper documentation (e.g., probate order, affidavit of heirship) to verify ownership before processing a sale. They need assurance that the seller has the legal authority to convey the property.

It’s always a good idea to consult with a Texas real estate attorney or probate attorney to determine the exact steps you need to take based on your specific situation.
