Missouri · Spouse signatureMissouri spouse signature to sell a house: the homestead rule and marital rights
Missouri protects a married seller's spouse in two ways. First, either spouse separately is debarred from and incapable of selling, mortgaging or alienating the homestead in any manner, and every such sale, mortgage or alienation is null and void – though nothing prevents the spouses from jointly conveying or mortgaging the homestead or any part of it (RSMo 513.475(2)). The homestead is the dwelling house, appurtenances and land used with it that the person uses as a homestead; the same section exempts up to $40,000 of its value from attachment and execution (513.475(1)). Second, any conveyance of real estate made by a married person at any time without the joinder or other written express assent of the spouse, duly acknowledged, is deemed to be in fraud of that spouse's marital rights if the spouse becomes a surviving spouse, unless the contrary is shown (474.150(2)); a gift in fraud of marital rights can, at the surviving spouse's election, be treated as a testamentary disposition and recovered from donees and persons who took without adequate consideration (474.150(1)).
What the statutes set
Homestead (RSMo 513.475(2))
Neither spouse alone may sell or mortgage it; such a sale or mortgage is void.
Joint conveyance (513.475(2))
Both spouses together may convey or mortgage the homestead.
Other real estate (474.150(2))
A conveyance without the spouse's joinder or acknowledged written assent is presumed in fraud of marital rights.
Gifts (474.150(1))
A surviving spouse may recover property given away in fraud of marital rights.
What the TC checks on a Missouri sale by a married seller
- Whether the seller is married, and whether the home is the seller's homestead.
- That the spouse signs the deed, or a written acknowledged assent, even if not on title.
- Any power of attorney a spouse will sign through, sent to the title company early.
Questions about Missouri spouse signatures
Does a spouse who isn't on title have to sign in Missouri?
For the homestead, yes – a sale or mortgage by either spouse alone is void (RSMo 513.475(2)). For other real estate, a conveyance without the spouse's joinder or written acknowledged assent is presumed to be in fraud of marital rights if the spouse survives (RSMo 474.150(2)).
Can Missouri spouses sell the homestead together?
Yes. The statute doesn't prevent the spouses from jointly conveying, mortgaging or otherwise disposing of the homestead (RSMo 513.475(2)).
