I would like to know how much I have to spend...

Good evening, I would like to ask what my father's rights are. I am separated (not married) I have a 7 year old son. It's been 5 years since the child is with the mother, who went abroad for a period of almost a year, so I could not see him. Then in the holidays I can not see it (birthday, Christmas and more). I spend a maintenance of € 150 a month, just for food because clothes or gifts like toys I buy them apart, I work part time 25 hours a week, I have to pay my wife and two children plus my mother to my country.
I would like to know how much I have to spend with my son, how many times a year can I see him (provided until now I have seen him twice in 2015 and now I should wait for school holidays because my mother does not want me to take him for a weekend so I see him only two or three times, I live in Milan and he now lives in San Benedetto del Tronto (he used to live in Milan).

The problem that I submit is composed of two distinct themes, certainly linked to each other, but certainly not proportional. There is in fact no correlation between the quantum of the maintenance allowance and your right of visit.
As regards exclusively the economic part white wedding dress with black lace, the obligation to contribute to the needs of the children weighs on both parents in proportion of their financial resources. Being the minor entrusted to the mother, who then provides for maintenance in direct form, you will have the obligation to pay a monthly allowance, as indeed already does. The judge, in determining the amount of the allowance for the child, considers the "current needs of the child", which are realized, not only, in the needs, but also in the legitimate aspirations of the child and, more generally in his prospects of life.

Assuming that a monthly allowance of € 150 is already to be considered quite small, if its economic condition has undergone (obviously pejorative) changes, such as a sizeable or significant reduction in the paycheck, or even if its family loads have increased ( for example, for the birth of a new child) from the moment when the judge has established the amount of the allowance blue white wedding dresses, you can certainly request a reduction, even if it is objectively unlikely that you can fall below 100 € monthly.
