A NSW court has placed Victorian MP Peter Crisp on a good behaviour bond for one year after he failed to prevent the theft of firearms from his rural property.

The verdict quells fears Mr Crisp may lose his seat if handed a sentence with a minimum jail time of five years.

The MP, who has a property on the NSW side of the Murray River but represents the electorate of Mildura, initially faced nine gun charges.

Three charges were withdrawn and he was found not guilty of another three at Wentworth Local Court on Monday.

Mr Crisp pleaded guilty to the three remaining charges, related to a failure to prevent the theft of the weapons.

No conviction was recorded against the MP.

The sentence will not prevent Mr Crisp from keeping his seat in the Victorian Legislative Council.
