Hundreds of employees at NSW's land titles registry are now uncertain about their future after a leaked draft contract revealed the future private operator could send their jobs out of the state.

During question time on Thursday, Opposition leader Luke Foley lifted up the "Land and Property Information (LPI) Concession Deed", marked "Sensitive: NSW Cabinet" and asked Premier Gladys Berejiklian whether these jobs would stay in NSW.

"Premier, I refer to this that's marked 'Sensitive: NSW Cabinet' - another leak from your leaky government - it's the draft contract for the privatisation of LPI," he said.

"Will you, Premier, at the very least make the commitment now, to include in the final contract, an absolute requirement to keep all of the several hundred LPI jobs in NSW, given that nowhere in these 232 pages of information in your draft contract is there any requirement to keep any jobs in this state?"
