Adverse possession requires the possessor to use the land without the true owner's permission. If the neighbored "is allowed" by the true owner, then the neighbor likely cannot succeed in claiming adverse possession.
The best thing to do likely is to write everything up and get the required signatures so that there is written evidence that permission was given.
A cautious landowner may even not allow any permission.
You should review the specific facts with your attorney to find out your legal options.
I agree with the previous answer a written and signed letter of permission would negate adverse possession. Better yet a revocable license to use the path would be better and could be properly drafted at a low cost and be enforceable and then you could terminate the use upon development, a time period , or at will.
