Good receipt for sale proceeds

A and B held a property as tenants in common in equal shares for many years. Under a partnership agreement entered into long after the property had been acquired between A, B and the spouses of A and B the spouses of A and B acquired beneficial interests in the property jointly with A and B as it became an asset of the partnership and they both had a share of capital. The registered title remained vested in A and B. A then dies and C and D, as executors of A, become registered proprietors with B.
B then dies and the property is sold by C and D. Can C and D get a good receipt for the 50% share of the sale proceeds to which B was originally entitled from the executors of B without further enquiry into entitlement to the beneficial interest originally held by B alone?
