Mr. Lerch provided me with highly professional, calm, and dedicated support throughout my legal proceedings.

Step 1
You send the lease and the adjustment notice and explain the situation.
Step 2
I review the clause, the calculation, and the legal starting point.
Step 3
You receive clear guidance on whether the adjustment appears valid and how to respond.
Step 4
If further action makes sense, we agree on the next steps in a structured way.
Dr. Philipp Lerch handles tenancy matters with a focus on clear legal assessment, understandable communication, and practical next steps. In index-rent and step-rent matters, it often matters to separate the contractual model from the specific adjustment being demanded.
