If you suspect the integrity of your lawyer you have two options and either of which can be followed by terminating the services of this lawyer"
Engage a new lawyer and fight out your case through your new lawyer by obtaining NOC from previous lawyer;
By filing a memo before the concerned court stating that yo have disengaged the existing lawyer and would like to fight your case as party in person, for this you can take advise and guidance outside the court from any skilled lawyer to follow up the case yourself.
Yo cannot meet the judge in person for this except that you can express your feelings about this in the open court during court hours.
If at all you suspect your lawyer to have taken bribe from the opposite lawyer and have clinching evidence for this to establish your lawyer's breach of trust, you can submit a complaint with the local bar association besides escalating the matter with the state bar council too seeking proper action against the erring lawyer.
