Speer's lawyer, Donna Carroll of Bay Legal, said the money left over from the sale was in the hands of the Public Trust, the executor of the father's estate, but the Public Trust was waiting for a High Court proceeding before it could release the money.
The proceeding was needed because the Public Trust received the sale money when it was acting in a role other than estate executor
Carroll said she spoke to the son who made "under-the-radar implicit" comments regarding any attempt to make him leave before he received the money left over from the sale.
Speer said police gave the man until Monday to be out of the house and he hopes to start renovating soon because he has to be out of his current home next month.
A police spokesman said it did not routinely serve trespass notices but people with safety concerns were "strongly advised" to get in touch with police.
No one appeared to be home when Hawke's Bay Today visited the house and attempts to contact the son were unsuccessful.
