Short sale - homestead question

I’m in negotiations with the bank on a short sale and wanted to know if I need to have some sort of homestead release from the owner?

It’s their primary home but they moved out…a year and 1/2 ago and their bankruptcy has already been discharged.

Does the owner still have the right to claim the house as his primary homestead after I have negotiated a sale price with the bank and purchased the property?

Thank you.

In short, no the previous owners do not have a right to claim homestead once title transfers.
