A woman was injured after her partner tipped her out of the bed, the court heard.
Robert Freeman, 37, of Hobart Road, Grantham, pleaded guilty to assault by beating on March 6.
The court heard how after a night out at a boxing match with his partner, her son and his girlfriend, they returned home and were joined by a friend of the son.
However, Freeman was getting annoyed about something and his partner decided to go to bed. Sometime later, she woke up to him storming into the bedroom and tipping the bed over with her in it, causing her to fall hard on the floor.
She made her way to the hallway, where her son’s girlfriend told Freeman to leave her alone, and another of her four children came out to see what was happening.
She was then shoved again, and the whole incident saw her suffer injuries to the back of her head, upper leg and right hand, detailed prosecutor Jim Clare.
Simon Cobb, defending, explained that the row had started because Freeman wasn’t happy about the son’s friend smoking cannabis in the house.
He argued that his client had pushed the victim in the hallway, but had not punched her, as she had testified. Mr Cobb added that it was a long-term relationship lasting 11 years, and that it was going to continue.
In a probation report given to the court by Kiran Patel, Freeman admitted police had come to the house previously when they had argued, but denied any violence was involved.
Mr Cobb said Freeman already had a debt to the court because he was fined in November for an assault on a doorman. He said a community penalty would not work as Freeman worked as a lorry driver and was abroad most of the time.
Freeman received a conditional discharge for 12 months, and must pay £85 in costs and a £15 victim surcharge.
