If you're a brother of a lodge and would like to demit and look for other lodges to join, how would the brother search for the lodges? Can they take help of regional grand lodge?

A Freemason demits from a lodge by submitting a voluntary resignation of membership, provided he is in good standing and free from all financial arrears or disciplinary charges 121. Upon accepting the resignation, the lodge issues a demit—a formal certificate acknowledging the withdrawal and attesting that the brother is clear of the lodge's books 1. While an individual member holds the right to demit at his own pleasure, historical regulations restricted groups of brethren from withdrawing simultaneously without a dispensation unless the lodge had become over-populous 21.

To join another lodge, the demitted Mason presents his certificate of demit or withdrawal to the prospective lodge as evidence of his previous good standing and regular acceptation 1. Under older codes and modern regulations alike, an applicant cannot be admitted into a new lodge without providing such documentation or ensuring the receiving lodge is informed of his standing 1.

The provided sources do not detail the role or involvement of a Provincial Grand Lodge or District Grand Lodge in assisting demitted Masons as they search for new lodges.
