Michael Lohan has retained the services of attorney Lisa Bloom (who happens to be power lawyer Gloria Allred's daughter) to represent him in what is becoming a LEGAL battle to try to get help for his daughters Lindsay and Ali.

Meanwhile, the girls' mom Dina is speaking out, saying her daughters are seeking restraining orders against their father after he burst into Lindsay's apartment last week with police officers in tow. Michael tells X17 he hasn't been served with any papers as of yet, but that if he is, he'll fight it. He says such a RO would be illegal because he was accompanied by police.

Bloom has released a statement addressing Michael's potential legal strategies to his daughter under control: "The law affords a parent who believes his adult child is not in control of her health and welfare a number of legal options. As of now, all options are open."

And in fact, Michael told us if a judge doesn't order Lindsay to rehab, he will seek conservatorship over her (a la Jamie Spears with Britney).

Bloom's statement says Michael doesn't want Lindsay to become another sad Hollywood headline: "He intends to do everything in his power to prevent Lindsay from becoming another Marilyn Monroe, Anna Nicole Smith, Michael Jackson, Heath Ledger, or Corey Haim."
