Wouldn't it need to be "al muhamy yekun fi alamania?"
It literally just says "The lawyer in Germany."
Yes, this is how Arabic works. We don't use the verb "to be" in forming statements (Russian is somewhat similar too). This type of sentences is called Nominal sentences; They start with a noun, and can be completed without a verb as well, like above.
If your sentence means (the lawyer "who is" in Germany) - in short form - then that would be المحامي الذي في ألمانيا where الذي means "who" (masculine).
