2. Paul’s definition:
”The essence of the obligation is not
make some things or servitudes
ours but to enforce second party to
gives us something or to provide
us with service”
4. Development of obligation:
* initial source of obligation:
damages done to estate of another
pater familias
* development of contracts due to
need to use someone else estate
5. Obligation as a legal relationship:
The obligation (obligatio) is a legal
relationship between two parties, one
of which is a creditor (creditor) and the
other debtor (debitor).
6. Obligation is build on the principle of
equality of contracting parties, which
means that creditor has no power over
debtor.
Obligation was not only a legal
relationship, but was also treated as
property (part of res incorporales –
immaterial property) which can be
subject of businnes transactions.
7. Obligation and actio (suit)
In Roman law obligation was strictly
bonded to specific suit – without suit
obligation wasn’t enforceable.
New obligations was created by adding
judicial provisions to new types of
agreements.
8. Relations not covered by any actio could
be subject of granting special provision
by pretor.
Pretor could grant actio in factum – suit
build on facts that were foundation of
parties relationship.
10. Origin of obligation
in Gaius’s Res cottidianae
I. Contracts
II. Torts
III. Various types of causes.

in Corpus Iuris Civilis
I. Contracts
II. Torts
III. Obligation arising from situation that
resembles contract (quasi ex
contractu)
IV. Obligation arising from illict act not

12. Development of contractual obligation
* numerus clausus of contracts in archaic
roman law
* rise of unnamed contracts - enforceable if
one of the parties performed their duties
* liberalization of formalities in case of oral
contract of stipulation
* genesis of pacta sunt servanda principle:
„Pacta quantumcunque nuda servanda” -
All „naked” contracts should be protected
(Decretals of Gregory IX)
13. Civil obligations
Where enforceable by law, which means:
1. They could be a subject of civil litigation
2. They were legal foundation of executing
one’s rights
14. Natural obligations
Contrary to civil obligations they weren’t
enforceable by law, which means they
weren’t protected by suit and weren’t
basis for execution.
15. Natural obligations
This type of obligation was usually effect of
contracts made by:
• Slaves
• Persons under patria potestas
• Persons under tutelage (minor and women)

* Person that provided peculium could cover his
expenses based on that type of obligation in first
place before other creditors
17. Unilaterly bidding contracts
This type of obligation had very simple
structure: only one party was a creditor
and only one was a debtor.
In civil litigation only creditor possesed a
suit.
Usually it was actio stricti iuris.
Example: contract of loan
18. Bilaterally biding contracts (perfect)
* both sides were creditors and debtors to
each other
* both sides possessed actiones to exercise their
rights in the civil litigation
* principle of equivalence of provisions
19. Bilaterally biding contracts (imperfect)
* at the start they looked like unilaterally binding
obligations
* in some causes another obligation bond within
the same contract and between the same parties
could arise - for example in case of damages
caused by the object of deposit in the estate of
depositary
* this second obligation had opposite directions -
debtor of primary obligation become creditor and
vice versa
20. Stricti iuris obligations
* oldest and simplest type of obligations
* upon evaluation judge didn’t considered
parties performance after conclusion of
contract but examined initial party agreements
21. Bonae fidei obligations
* judge could take into account various
aspects of contractual relationship - such
as pacta adiecta, interest or estate
revenue
* judge could award compensation to one
party due to other party performance
22. Joint obligation (joint liability)
* despite the fact that there are multiple debtors or
creditors there was only one debt to fulfill
* in case of one debtor who fulfill whole debt in name
of the others was created grounds for recourse claims
23. Subject of obligation
Subject of obligation in a one of the
following forms:
• dare - to give something to someone

terms which had different effects:
* when subject of obligation was specific item in
case of it’s loss the risk was borne by creditor
* when subject of obligation was describe as a
item which hade some defined parameters it
was always possible (in case of loss or
damage) to provide creditor with new item
27. Impossibility of claim
* Impossibilium nulla obligatio as a
principle
* Impossibility after agreement:
- case of vis maior

timely manner
* in case of obligation without specific due
date summon was required
* in case of obligation with specific due data
expiration of this period was sufficient
* in case of obligation arisen from a tort

33. Fault (culpa)
• Culpa lata – great negligence;
• Culpa levis – lesser degree of negligence
which consist neglect of care that we used
to expect from:

good host
b) culpa in concreto – from debtor who act in
his own affairs
34. Principles of liability
• Primary principle: fault as a ground for legal
liability
• Secondary principles: custodia and risk
(quasi-delicts)
• „Magna culpa dolus est” – great negligence
had the same legal effects as intentional
fault
• „Dolus semper praestatur” - liability in case
of intentional fault couldn’t be excluded
• „Casus a nullo praestatur” - no one is
responsible for fortuity
35. How to secure obligations?
If suability and enforceability of obligation
wasn’t enough creditor might want to
implement some additional securities to
primary agreement.
