A partition agreement divides, or partitions, a married couple's community estate into two separate estates. It is sometimes called a post-nuptial or post-marital agreement and is similar to a prenuptial agreement, except that it is executed by a married couple.
Even if only one spouse's name is on the deed, any property bought during the marriage is presumed to be community property, unless it was bought with separate property funds. The spouse claiming it as separate property must prove it in court.
There's no way that you could force him to sell you his share. He would still be a ``co owner'' of the property, and Texas law does not allow for the forced sale or transfer of one nonmarital co-owners interest in the property to the other. If you were married, the court could force this, but not if you're not married.
Texas is one of nine states that is a community property jurisdiction. In general, this means that any property acquired by a couple during their marriage (with a few exceptions) is equally owned by both spouses. This can have a profound effect on the dissolution of property during divorce proceedings.
Property acquired during the marriage (outside of the noted exceptions) is considered community property. The spouses can, however, agree to convert (or “transmute”) community property into separate property. In Texas, this is done via a written agreement establishing a partition or exchange between the parties.
Code § 4.102. Current with legislation from the 2023 Regular and Special Sessions signed by the Governor as of November 21, 2023. At any time, the spouses may partition or exchange between themselves all or part of their community property, then existing or to be acquired, as the spouses may desire.
There are two potential pathways in seeking a partition: Partitions may be in kind (meaning that property is divided into separate parcels and each parcel is allotted to a separate owner) or by sale (meaning that property is sold and sale proceeds are divided among the owners).
Potential solutions for dividing inherited property include selling the property and dividing the proceeds, providing siblings with co-ownership, and having one sibling buy out the other siblings.
