Does the AI always accept requests to Claim Inheritance?

[durbal]

I've never had one denied and it seems a bit easy to grab clay through inheritance requests.  I was playing a Semigalla with a whole one province and one army and claimed land from Poland who was a Great Power and they're like 'sure but we'll be kinda mad'.  Seemed like something they absolutely should not have done.

No. Depends on the relationship.  I've had a claim denied.

It's quite a complex decision:

 

	pros = 5 // a.k.a. peace points
	{
		pc_we_have_good_relation { base = 2; max = 30; pow = 0.5 }
		pc_our_army_is_weaker { max = 40 }
		pc_we_have_trade = 5
		pc_our_trade_level { max = 15 }
		pc_their_trade_level { max = 15 }
		pc_we_have_nap = 10
		pc_we_are_allies = 20
		pc_we_share_same_religion = 10
		pc_we_have_rebels {	max = 25; per_rebel = 5 }
		pc_we_have_war_exhaustion {	max = 50 }
		pc_we_have_too_many_wars { max = 50; at_war_base = 10; per_additional_war = 20 }
		pc_we_need_peace_time { max = 20; minutes = 20; pow = 2 }
		pc_too_many_global_wars { max = 20; num_wars = 20 }
		pc_our_authority_is_low { per_negative_point = 10 }
		pc_their_diplomat_skill_level { max = 15 }
		pc_we_are_their_vassal = 20
		pc_they_plan_invasion_against_us { max = 30; per_ally_province = 3 }
		pc_their_influence_in_our_kingdom = 30
	}

	cons = 50 // a.k.a. war points
	{	
		pc_we_have_no_border = 20
		pc_they_are_too_far = 50 { threshold = 3 }
		pc_they_are_our_vassal = 20
		pc_we_have_bad_relation	{ max = 30;	pow = 2 }
		pc_our_army_is_stronger { max = 30 }
		pc_they_rule_our_people { our_kingdom = 10; our_culture = 5; our_culture_family = 2; max = 30 }
		pc_they_rule_our_lands	{ per_historical_realm = 5; per_core_realm = 5;	max = 30 }
		pc_we_are_X_times_larger = 20 {	X = 2 ; added_realms = 2}
		pc_they_are_excommunicated_and_we_are_catholic = 20
		pc_we_want_to_liberate_rome = 100
		pc_they_hold_our_holy_cities_and_we_are_Sunni {	shia_control = 10; other_religion_control = 50 }
		pc_they_hold_Baghdad_and_we_are_Shia { sunni_control = 10; other_religion_control = 70 }
		pc_we_both_have_under_X_towns = 30 { X = 3 } 
		pc_there_are_our_loyalists = 10
		pc_they_have_rebels	{ max = 15; per_rebel = 3 }
		pc_they_have_different_religion = 5
	}

If the amount of peace points is equal or higher than the war points, the AI accepts.
