Getting a Verpflichtungserklärung

I need to get a Verpflichtungserklärung for my relatives who are visting me. I am registered in Munich. Stupid me, forgot somepapers in my office which is in Miesbach. Since I am running short of time, can I get it done in Miesbach Rathaus itself (I heard there is one there!). If yes, how do I find the location of the rathaus?

Type "Miesbach Rathaus" into Google and the first result will give you the address and telephone number of said institution. A quick phonecall will determine whether you can do whatever it is you are trying to do.

I was planning to get the papers tommorow morning. That leaves me no time to call and find out:(

Its never a good idea to wait until last minute to do ANYTHING that requires the German bureaucracy...they could have you running around the whole city trying to gather other documents.then you have to fight with weird business hours, especially on a Friday.
Just my personal experience though...Goodluck.
