Good morning Sik90005,
While it is not recommended, the answer to your question is, "Yes, you may retain a new Attorney to represent you even after you have signed the contract." You will need to formally release the original Attorney in writing and retain the new Attorney and advise all parties of the change immediately to avoid confusion and delays in the process of buying your home.
