My husband was left half of a 2-family home in trust when my mother-in-law passed. The other half belongs to his sister. My husband was sole heir in his mother's will. There is now a lein on the house for $179,000. the house is selling for $545,000. His sister is claiming no legal responsibility to the lein due to the fact that the lein is for my mother-in-law, and that she was left nothing in the will. Legally speaking, after the sale of the house is split in 2, should the lein also be split in half for each, or is it my husband's sole responsibility?
I would really appreciate any help I can get in this matter
