Managing money well is also about being regular: you have to do it regularly (just like you were taught to brush your teeth from a young age!). The good news is that you don't have to do your accounts morning and night: three times a month is usually enough. For guardianship of a loved one who doesn't know how to spend their money, you'll need to file a case. In fact, this is the file you use to submit your application to the district court. This will include several things about the loved one you want to protect.
