Michigan Compiled Laws, Chapter 462. Railroads § 462.250

Sec. 250. If a railroad company desires to acquire the right-of-way through any lands or premises, the company before or after proceedings are commenced for that purpose, may offer to the owner or owners of the lands or premises, any sum of money the company determines to be sufficient for the damages for the right-of-way, together with the costs to the time of making the offer. If it appears that the amount offered was sufficient to pay the damages, plus 25%, and the costs of the proceedings up to the time of the offer, the owner or owners of the lands or premises shall not be entitled to recover or collect any costs incurred subsequent to the time of the offer, but shall be liable to the railroad company for the costs incurred by it subsequent to the offer.
