A couple lied on immigration forms to help a three-year-old girl enter the UK, Lincoln Crown Court was told.
Wolfgang Unwin and his wife, Charito, claimed the child was their own in an application made in 2012 for a settlement visa for the child.
Phil Howes, prosecuting, said the initial application was made online before the couple went to the UK visa application centre in Manila, in the Philippines, with a forged birth certificate.
The document wrongly claimed the couple were the parents of the child and that she was born on December 1, 2009.
The couple were asked to produce further documents to prove that Mrs Unwin was pregnant at the relevant time but she claimed that the she could not produce anything as she had not visited a GP in the UK.
Mr Howes said: “A number of photographs were sent to the authorities which were said to be Charito Unwin and Wolfgang Unwin with the young girl.”
But in November 2012 Mrs Unwin was arrested at their home in Grantham and her husband was detained at Heathrow.
Charito Unwin later told police she thought it best for the girl if they could get her into the UK and they thought the adoption process was complicated. Her husband said he wasn’t aware of the real parents’ names but they were related to his wife.
Wolfgang Unwin, 68, and Charito Unwin, 33, both of Albion Close, Grantham, each admitted assisting illegal entry into the UK in August 2012 by trying to pass off the three-year-old as their own child.
Wolfgang Unwin was jailed for six months. Charito Unwin was given a six-month jail sentence suspended for a year with 12 months’ supervision.
