The Mean Girls actress is accused of failing to honour a deal to give snapper Scot Nathan a one per cent share in her clothing line 6126 in exchange for a photoshoot.
He launched legal action against Lohan in April (10) and a process server attempted to visit the troubled star at the Betty Ford Clinic in Rancho Mirage, California earlier this month (17Oct10) – but he was denied access and instead gave the papers to the security guard.
However, the action will not count as court documents cannot be handed to security, reports TMZ.com.
Lohan was sentenced to a further three months of treatment on Friday (22Oct10) for violating her probation after failing two court-ordered drug tests in September (10).
She will remain at the Betty Ford Clinic until at least 3 January (11).
