"There's quite obviously demand for legal advice here", Jens Lorek said on Thursday.
"The trouble is, people are afraid of making fools of themselves in court".
Lorek, a lawyer based in the eastern city of Dresden who specialises in social and labour law, said he hoped to get more clients by taking on the unusual work.
He has yet to win any abduction claims, but says there are plenty of potential clients, noting that extra-terrestrial watchdogs report hundreds of alien assaults every year.
"These people could appeal for therapies or cures," he said.
Lorek is pinning his hopes for success on a German law which grants kidnap victims the right to claim state compensation.
Asked if he was worried he might look ridiculous by seeking justice for clients haunted by aliens, Lorek was unfazed.
"Nobody has laughed about it up until now".
