Suing a mortgagee for non performance

[Sara Als.]

I have a second position mortgage deed (I am the lender) on a property in FL but the Mortgagee and the contract holder is in CA. He is in breach of the mortgage agreement:

1) the note was up summer '19 and he did not pay it off neither will record an extension when i asked

2) he hasn't paid his monthly interest dues on the mortgage for close to 6 months now

3) he was buying time with me by giving me various excuses and now completely ignoring my calls and text msgs

This person is actively marketing his projects/properties/investments here on BPs which is where him and I got connected over a year ago. 

I want to initiate a law suit for non performance. Any Attorneys here from CA or referrals? 

Thanks,

Sara
