A contract signed by person A does not bind person B, even if B ended up buying, inheriting, or otherwise taking over the contract, unless B actually agreed to be bound under the agreement: one person may *not* legally bind another. Based on what you write, when the property became your husband's, the contract was effectively terminated. By continuing to use the management company, you would be responsible to pay them for all working the actually *did* (you can't get another's work for free), but did so under an oral agreement, terminable at will: that is, you have to pay them up through when the agreement terminated, but not going on into the future after the termination of their represenation or management of your property.
