A Queensland law student who masqueraded as a solicitor on social media and in court has found himself before a magistrate for all the wrong reasons.

Jacob Reichman, 22, was fined $1000 on Wednesday after pleading guilty to representing himself as a legal practitioner and engaging in legal practice when he wasn't entitled to.

The aspiring lawyer was also ordered to pay $1084 in legal costs.

Brisbane Magistrates Court heard that Reichman introduced himself as a solicitor for Gold Coast firm Michelle Porcheron Lawyers during several appearances in Beenleigh Magistrates Court in 2013.

He was actually a second-year law student and a clerk for barrister Chris Rosser. He was at court to seek adjournments for one of Mr Rosser's clients.
