DSS is nearly 13 and we see him every other weekend or thereabouts. Sometimes not as he has parties etc at the weekend.
DH is definitely not a 'Disney dad' but DSS for sure is a lazy toe tag!
We don't see him very much but as the oldest of 6 brothers (3 ours, 2 his mum's - all 5 and under) he has been pandered to an spoiled. He doesn't do anything chore-wise round the house here or there and can barely get his pants in the wash basket.
Is it unreasonable to say that from now on, he has specific jobs like lay the table, keep his clothes tidied away (he shares a room) etc? Both DH and I think we should as his laziness has expectations will only get worse as he gets older, but equally we don't want him to feel like unpaid weekend help!! 
I also need advice on how to get him to look after his and other people's belongings but I won't go into that here.
Thanks in advance.
