Remember, though, that it is sometimes necessary to do research on other family lines to learn about the one you want. You should not accept a report that does not cite the sources used for research. Keep in mind that time often is spent searching just to prove that there are no records available. Your researcher should report to you on all of the records he has checked and the results. Sometimes you must pay for time just to learn that no records are available, but you then have some proof that your elusive ancestor may not have been in that location after all.
Many researchers expect a retainer before beginning work.
This is a safeguard for both of you. The retainer should be set aside until work is completed and a refund made if it is not completely spent. Unless it is a very simple job, most researchers prefer to report back occasionally to make sure the research is being completed as you desire. If you get new information from another source, send it to your researcher who may be able to use it to your advantage. Also, remember to put your name and address on all documents.
