I cannot tell you whether the obligation to pay the maintenance fees will end when the husband dies because I am not an attorney. However, below is some basic info on Quitclaim deeds.
Interest in the properties can be transferred from the two people (a married couple) to just the one person (the husband) by a Quitclaim Deed. A Quitclaim Deed is typically used to transfer property among people well-known to each other (such as immediate family members) because these people (here the married couple)
already definitively know whether there are liens or encumbrances on the property such a mortgage and the details. Anyway, the selling price ("consideration") is typically specified to be one dollar. A quitclaim deed will need to be prepared for each existing deed (timeshare). Be aware that that different states & counties within those states may have different formats/legal wording requirements for deeds. This means that if the various timeshares are all located in different states/counties, each Quitclaim deed may need to have a slightly different format/legal wording to comply with that county's requirements.
Your friend must first obtain certified copies of all of the existing deeds (if she does not already have copies). She can obtain a certified copy by contacting the counties in which the timeshares are located. There will be a small fee to be mailed a certified copy. She will need to EXACTLY copy much of the information in these deeds (especially the exact legal description of the property) to prepare the Quitclaim deeds.
Your friend may consider the shortest duration (lowest cost) membership at
www.RocketLawyer.com to prepare the QuitClaim deeds. I believe that it is less than $100. The "free" 7-day membership is pretty useless. They have a Quitclaim deed preparation tool there.
The deeds are then signed by the GRANTOR(S) (the Grantors are the sellers which here would be both the husband & wife) in front of witnesses who also sign and a Notary Public who then stamps & signs.
The quitclaim deeds are then filed in their respective counties. The county will charge a small fee for this.
Finally, the Quitclaim deeds are sent to the timeshare company (for example - Marriott) so they can update their records. Contact them first to obtain the forms & procedure. They may charge up to a few hundred dollars processing fee for this.
