Remember , if you take the advice of the agents that say go ahead and file the Quit Claim Deed you may remove the interest of the other party but who has interest or will have interest in that partys propertyYou have not removed any claims against the 2nd partys partys property.This is not something you know even if you are a relative. That is why we say always go to a Title Company or Attorney.
All a quit claim does is say - if I have any good claim to this property you may have it, if I have any poor or prejudiced claim to this property you may have that as well. Unless any transfer is done properly, future claims against that person can also affect the property.
I will tell you that I have only experienced and heard of problems with quit claim deeds and if any relative asked me I would say NO.
Real Estate Attorneys attached to title offices do not charge much to make out the proper work. I hate to say it but we would not have real estate attorneys unless there was a reason, and you just found one of the biggest reasons.
This is a question to be answered by a title officer or a real estate attorney.
If you are have hired a Realtor to help you in the sale, then ask them. If you are selling on your own...be very careful.`
