Thank you for your response.
In 2009 the legislation concerning spousal support changed and since that time nothing is sure anymore as it used to be.
So now jurisdiction depends on the circumstances .
After the year of separation however the spouse who has not worked fulltime during marriage is obliged to do so and has to look for work and write 20 job applications per month.
If he does not succeed the income he could earn by working fulltime is added to his income as a fictitious income.
This is if he is not too ill to work fulltime for which you may need a medical expertise.
So she may have to pay support for longer than a year
As to the houseIf the house is sold the capital every spouse gets out of it does not count as income only the interest you could get on that capital does
So if everyome gets , say , 200,000 Euro out of selling the house he does not have to live of his share of the money but if he gets interest out of it or could get interest out of it counts as income or fictitious income
So she will have to pay less support because he will have income of his own
I would really recommend your sister take a good solictor who should be a Fachanwalt für Familienrecht ( divorce lawyer) like myself
I hope I was able to help and would very much appreciate getting a positive rating because this is how I get my share out of the deposit you made
Thank you so much and all my best wishes for your sister
