Greetings Listmates

I received a request for a referral for a PA real estate attorney.  Client and husband signed a contract to purchase a new construction home in PA from an established developer. Construction has commenced.  I believe the foundation is in place.  Recently the husband has been diagnosed with Alzheimer.  The client wants representation to terminate the contract and receive her down payment back in full or as much as possible. 

Please forward names of professionals who can address this matter. An elder law attorney may also be helpful. 

Thanks
