Michael Lohan's lawyer has just sent TMZ a statement, saying unless Lindsay Lohan and her lawyer sit down and talk to her dad about the obvious problems, they will go to court to force the issue.
Attorney Lisa Bloom says it's clear Lindsay has a problem ... with photos surfacing nightly of Lindsay clubbing and appearing "under the influence of alcohol or substances."
Bloom says Michael will take "any and all appropriate legal action to save and protect his daughter."
As for what legal options ... Bloom says she's not foreclosing anything.
Bloom adds ... if Lindsay doesn't meet with Michael in the next few days, "Michael is prepared to pursue other legal action towards his one and only goal: to save and protect his daughter."
