The League One club remain in administration while prospective new owners Portsmouth Supporters' Trust try to agree a deal to buy Fratton Park from former owners Portpin, who hold the stadium as security.
Portpin have rejected a £2.75m offer, and administrators PKF hope the High Court will force through the sale by agreeing with their preferred bidders' valuation.
But PKF, who fear Portsmouth will be liquidated if the sale of Fratton Park does not go through, have now asked for a delay of 28 days while they "take stock and assess options."
And the presiding judge has agreed to adjourn the case until January 15, although that date is subject to change.
Colin Farmery of the Portsmouth Supporters Trust told Sky Sports News: "It's not ideal but we want to get the right deal for the football club and if it takes an extra day, a week or month I think there is the will to make sure that happens."
