你无需请律师，自己搞定。下次再有律师找你做专业咨询，把马里兰州的这段州法先念出来，

与律师共同学习学习。（估计那律师是欺你不懂事）

(3) Fees and Expenses of Deposition. Unless the court orders otherwise on the ground of manifest injustice, the party seeking discovery: (A) shall pay each expert a reasonable fee, at a rate not exceeding the rate charged by the expert for time spent preparing for a deposition, for the time spent in attending a deposition and for the time and expenses reasonably incurred in travel to and from the deposition; and (B) when obtaining discovery under subsection (g)(2) of this Rule, shall pay each expert a reasonable fee for preparing for the deposition.
