Looking for advice please, my DH recently got made redundant. He agreed to be paid for his 3 month’s notice plus severance and holiday owed. His contract ended at end April and in that months payroll he got paid a lump sum for April pay and the rest of the package. When it arrived 2 weeks ago it was slightly more than anticipated but we didn’t question it too much as assumed it was due to the accrued holiday and the tax calculations. I don’t think he yet has his P45.
His ex employer has today told him they have accidentally paid him his April salary twice and they want him to pay it back. This is entirely their error. As he is no longer employed by them is he legally obliged to pay it back? And how would they be able to get it back if he refuses to pay it back?
