I know this is probably not possible but let's say I have a model with two properties.

I write a ValidationAttribute for one of the properties. Can that VA look at the other property and make a decision?

So;

public class QuickQuote
{
    public String state { get; set; }

    [MyRequiredValidator(ErrorMessage = "Error msg")]
    public String familyType { get; set; }

So in the above example, can the validator test to see what's in the "state" property and take that into consideration when validating "familyType"?

I know I can probably save the object to the session but would like to avoid any saving of state if possible.
