Ms. Bharati Mitra,
Now find out that husband left his residence for a few days for his personal work or abandoned the residence for the purpose of avoiding the court notice/summons. If the case is former, once he comes back to his residence, then ask the court to send the process of service again to the same address. If the situation is latter, i.e., he abandoned his residence for the purpose of avoiding the court notice, then you can do the following things:
(1) File application of fresh address of husband with a request to issue process of service;
(2) You can / shall also file the address of his office, where he generally works with a request that notice to be served through his head of the department;
(3) If you are not aware of addresses mentioned in 1 and 2, you get the notices issued twice and thrice on the old address and after they return undelivered, you can move application for publication of notice in the local newspaper. Once the notice is published in the newspaper and he does not turn up, the court will proceed ex-parte.
