property rights (conjugal or not)

hi atty., i am now separated with my husband. he has now a new common wife who's staying in our used-to-be residence before. we haven't yet worked out with annulment or legal separation in the court. i am currently on the process of buying my own house and lot etc. and of course i needed pag-ibig agency to help with my financial obligation as per settling the mode of payment. now as advice by one of their staff i need to get my husband's consent as per buying the said property. can't i buy any properties that would not be a conjugal property? or is there any possible ways to acquire properties while under marriage but will not be subjected as conjugal property? thanks in advance.

he will own half the value of your new house unless you are granted a judicial order separating your property
