Hi there!
For the shake of knowing, the link provided below serves as a valuable reference for individuals who confidently assert football (and futsal?) rules in their statements, even when they might not possess a deep understanding of the regulations. It can help clarify the nuances of handball situations in defensive positions.

In my perspective, I believe it's inappropriate to call handballs in defensive positions during our friendly games, especially when there's no clear opportunity for a goal to be prevented. This is particularly true when the ball comes from the defender, and the hand is in a natural position, with no intention of handling the ball which it was precisly my handball during the game. At most, my handball is up be interpreted either way by a qualified referee.

PS. I am assuming that futsal share the same regulations for the handballs as in football.

ho hard feelings, just commenting the regulation

Interestingly, someone else has shared the futsal regulations regarding handballs in another group I'm a part of. It appears that the rules surrounding handballs are even more permissive than I had initially thought.

I hope that the provided information, we will help us to have a better grip before calling (or not) a handball.

Below I copy/paste the FIFA futsal handball rules which are written at page 59:

Except for goalkeepers in their penalty area, it is an offence if a player:
• deliberately touches the ball with his/her hand or arm, including moving
his/her hand or arm towards the ball;
• gains possession/control of the ball after it has touched his/her hand or
arm and then:
• scores in the opponents’ goal;
• creates a goalscoring opportunity.
Except for goalkeepers in their penalty area, it is usually an offence if a
player:
• touches the ball with his/her hand or arm when:
• the hand or arm has made his/her body unnaturally bigger;
• the hand or arm is above or beyond his/her shoulder level (unless the
player deliberately plays the ball with another part of the body and it
then touches his/her hand or arm).
The above offences apply even if the ball touches a player’s hand or arm
directly from the head or body (including the foot) of another player who
is close.
It is an offence if any player, including a goalkeeper, scores in the
opponents’ goal directly from his/her hand or arm, even if accidental.
Except for the above offences, it is not usually an offence if the ball
touches a player’s hand or arm:
• directly from the player’s own head or body (including the foot);
• directly from the head or body (including the foot) of another player
who is close;
• if the hand or arm is close to the body and does not make the body
unnaturally bigger;
• when a player falls and the hand or arm is between the body and the
ground to support the body, but not extended laterally or vertically
away from the body.

Jose, thanks for the guidelines, let's keep these in mind in the games 👍

Game tonight at Merihaka. See you there!

Another thing I have noticed that confuses some players is the ball out rule. Often from a further distance, the angle can be fooling to the eye. if the ball is touching the line, it is still in play. The ball is out of play when it has crossed the goal line or touch line, on the ground or in the air - the whole of the ball must be over the line.
