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.
PARTITION. A joint owner or claimant of real property or an interest in real property or a joint owner of personal property may compel a partition of the interest or the property among the joint owners or claimants under this chapter and the Texas Rules of Civil Procedure.
Every co-owner of an interest in the property (no matter how small) must agree in order for a voluntary partition to occur. The remedy when agreement cannot be reached is for one or more of the co-owners to seek a court-ordered division by means of a partition suit.
To win a partition action can take anywhere from a couple of months to reach a settlement agreement to a year or more if it goes to a court trial.
