The court convicted Mandeep Sharma, a resident of Mandi Gobindgarh, and also imposed a fine of Rs 10,000 on him.
In default of payment of fine, he will have to further undergo a sentence of 10 years, the court said.
The case was registered in December last year when Sharma's sister approached police and accused him of repeatedly raping her.
The 28-year-old woman told the police that she was married to a youth of Sangrur district and had two children.
In 2006, her brother visited her in-laws house and raped her, prosecution said, adding that when she approached her husband, he snapped all ties with her and she was forced to live with her brother.
Fatehgarh Sahib (Punjab): A local court on Friday sentenced a man to 10 years in prison for repeatedly raping his sister in 2006.
