Lord Malfoy wouldn't bother with Muggle lawyers, he'd use magic and take what he wants. Remember, he doesn't see Muggles as people. The only ones who could stop him from doing anything he wanted would be other magic-users.
The point about lawyers is just that Harry sees the wizard world as rather quaint and old-fashioned; Lucius is a big frog in a very tiny pond. Let the Masquerade be broken in any serious way, and within a year or two Muggle Britain will have produced anti-curse body armour (possibly made of tinfoil) and guns that will reliably break a wizard's shields. In other words, it's not just wizard lawyers that are cute; wizard soldiers are also fundamentally non-serious. This may not be actually true, but I think it is what Harry believes.
