Only one spouse signed a "view easement". Now what?

[Charlie MacPherson]

I'm trying to help a family member sell her house in Boothbay, Maine.  There was an offer that blew up because of a defect in a "view easement".  The buyer's attorney claimed that only one of the two spouses signed the easement.

There is a significant water view from their property, near the top of a hill.  If a builder were to construct a house in front of theirs, the view could be much less attractive.

Any ideas on how to proceed?
