Agree with Shri Gyan Prakash. Doctor or advocate, nobody will agree with second opinion, or with the patient or the client advising them. You can get information from forums like these, and only if you are fighting case party in person all the suggestions given by various advocates and legal advisors will be of help you as you yourself can put to use the information or advice that is given here. Just for your information I am putting this here.
When party is not accepting summons, next thing to do is,
1. File application to court asking newspaper notification one national and one local for three days on equal interval. Check which newspaper usually carries such notice from Family Court.
2. After publication of such notice, court can be asked to send summons through dasti service, ie via police of jurisdiction police station of the area where the respondent is staying. Even then if the respondent fails to recieve summons, then following must be done.
3. Application under section 65 of CRPC, asking court to do tom tom in the area where the respondent is living and pasting of summons on the conspicuous part of the building where the respondent is living.
After the pasting of summons and tom tom court to wait for 3 months for party to appear. Even after that the party does not appear, your advocate should give application to court for passing of exparte orders.
After exparte orders are passed, give EP application and ask court to proceed with attachment of property, issuing of warrant etc.
