Dear Customer ,
Thank you for posting your real property law question today.
The action your sister and her husband would file is an action for quiet title to the property in WA STate.
She needs to file a petition in the Superior court for quiet title based upon contract.
She can also file a petition under the laws of equity, promissory estoppel and unjust enrichment for the the transfer of the property back into her name.
Because the son should have returned the property to your sister under contract he may have committed a criminal offense of fraudulent property transfer.
This can be reported to law enforcement.
"a) A transfer made or obligation incurred by a debtor is fraudulent as to a creditor whose claim arose before the transfer was made or the obligation was incurred if the debtor made the transfer or incurred the obligation without receiving a reasonably equivalent value in exchange for the transfer or obligation and the debtor was insolvent at that time or the debtor became insolvent as a result of the transfer or obligation."
