Transfer of property - right to maintenance????

you can ask maintenance. but  the said property is ancestral or not, and once registered and

transfered some one you could not claim  

here ancestral property means why he sold the property has to be ascertained and the reason is genuine then you cannot pray for attachment and about maintenance you can pray for interim maintenance for both of you and for this if you have any evidences like salary slip company details you have to mention in the petition 

If it is ancestral property in legal sense and not popular sense, then you can file a suit on behalf of your child to set aside the gift deed by declaring it null inrespect of  the only such part of the property, which your son is entitled as a legal heir.  The part of the property, which your husband is entitled as legal heir, he can gift to any one he likes.    Further, the date of gift deed has no relevance with the date of your filing the maintenance petiton, means that your filing the maintenance petition after the gift deed was registered will not affect your challenge of illegality of gift deed.
